Dictionaries are key-value pairs that allow you to store and access data efficiently using unique keys.

1) What is a Dictionary?

A dictionary is an unordered collection of items where each item is a key-value pair. Keys must be unique and immutable (like strings, numbers, or tuples), while values can be any type, including lists or other dictionaries.


# Example
person = {
    "name": "Alice",
    "age": 25,
    "city": "London"
}

empty_dict = {}
nested_dict = {
    "student1": {"name": "Bob", "age": 20},
    "student2": {"name": "Charlie", "age": 22}
}

2) Accessing Values

Access values using their keys.


person = {"name": "Alice", "age": 25, "city": "London"}

print(person["name"])   # Alice
print(person.get("age")) # 25

Note: Using a non-existing key with square brackets raises KeyError, but get() returns None or a default value.

3) Adding and Updating Items


person = {"name": "Alice", "age": 25}

# Add new key-value
person["city"] = "London"

# Update existing key
person["age"] = 26

print(person)
# Output: {'name': 'Alice', 'age': 26, 'city': 'London'}

4) Removing Items


person = {"name": "Alice", "age": 25, "city": "London"}

# Remove by key
del person["city"]

# Remove and return value
age = person.pop("age")

# Clear entire dictionary
person.clear()

print(person)
# Output: {}

5) Iterating through Dictionaries


person = {"name": "Alice", "age": 25, "city": "London"}

# Iterate keys
for key in person:
    print(key)

# Iterate values
for value in person.values():
    print(value)

# Iterate key-value pairs
for key, value in person.items():
    print(f"{key}: {value}")

6) Common Dictionary Methods

get(key, default) – Access value safely
keys() – Returns all keys
values() – Returns all values
items() – Returns all key-value pairs
update() – Merge another dictionary
pop(key) – Remove and return value
clear() – Remove all items

7) Common Mistakes

Using mutable types as keys (lists, dictionaries) → TypeError
Accessing non-existent keys without get() → KeyError
Confusing keys and values when iterating
Modifying dictionary size while iterating → unexpected behavior

🐍LAMDA FUNCTION

Sometimes, you need a quick, one-line function without the hassle of using def. That’s where lambda functions come in.

1) What is a Lambda Function?

A lambda function is a small, anonymous function defined using the keyword lambda. Unlike normal functions created with def, lambda functions:

Can have any number of arguments but only one expression.
Do not need a name (anonymous).
Return the value of the expression automatically (no return keyword needed).


# Syntax
lambda arguments: expression

# Example
square = lambda x: x * x
print(square(5))  # Output: 25

2) Basic Examples


# Add two numbers
add = lambda a, b: a + b
print(add(3, 4))  # Output: 7

# Check even or odd
is_even = lambda x: "Even" if x % 2 == 0 else "Odd"
print(is_even(5))  # Output: Odd

3) Why Use Lambda Functions?

Quick throwaway functions you don’t want to define with def.
Used with higher-order functions like map(), filter(), sorted(), and reduce().
Helps keep code shorter and cleaner for simple operations.

4) Using Lambda with `map()`, `filter()`, and `sorted()`


# Double each number using map()
nums = [1, 2, 3, 4, 5]
doubled = list(map(lambda x: x * 2, nums))
print(doubled)  # [2, 4, 6, 8, 10]

# Filter even numbers
evens = list(filter(lambda x: x % 2 == 0, nums))
print(evens)  # [2, 4]

# Sort by second element in tuple
pairs = [(1, 2), (3, 1), (5, 0)]
sorted_pairs = sorted(pairs, key=lambda x: x[1])
print(sorted_pairs)  # [(5, 0), (3, 1), (1, 2)]

5) Common Mistakes

Trying to write multiple statements: Lambda can only have one expression, not multiple lines.
Using for complex logic: If it gets too long, use def instead.
Forgetting it returns automatically: No need to use return.


# ❌ Invalid: multiple statements
lambda x: (y = x + 1; y * 2)  # SyntaxError

💡 Try It Yourself

Write a lambda function to find the cube of a number.
Use map() with lambda to convert a list of strings to uppercase.
Use filter() with lambda to get numbers divisible by 3 from a list.

🐍TIPS TO AVOID MISTAKES WORKING WITH BUILT-IN FUNCTIONS

🐍INTROSPECTION & UTILITIES

Python provides built-in functions to examine objects, check properties, and explore your code interactively. This is called introspection.

What is Introspection?

Introspection is the ability of a program to examine the type or properties of objects at runtime. Python provides several built-in functions for introspection.

Common Built-in Introspection & Utility Functions


# dir(): lists attributes and methods of an object
print(dir(list))

# type(): returns type of object
x = 10
print(type(x))

# isinstance(): checks if object is of a certain type
print(isinstance(x, int))   # True

# callable(): checks if object can be called (like functions)
def greet():
    print("Hello!")
print(callable(greet))      # True
print(callable(x))          # False

# id(): returns unique ID of object in memory
print(id(x))

# help(): shows documentation of object or function
help(len)

Common Mistakes

Calling dir() on an undefined variable → NameError
Forgetting parentheses for callable() → returns object info, not evaluation
Using help() incorrectly without an object → opens interactive help unexpectedly
Confusing type() and isinstance() when checking inheritance

💡 Try It Yourself

Use dir() on a string and a list.
Check if a variable is an integer using isinstance().
Check if a function is callable using callable().
Print the unique ID of two different variables using id().
Use help() on the sum function to see its documentation.

Ultimate Guide: Creating and Customizing Scatter Plots in Excel with Two Data Sets

Scatter plots are one of the most effective ways to visualize relationships between two variables in Microsoft Excel. But did you know you can also compare multiple datasets, use secondary axes, adjust scaling, and even save your chart as an image?

In this step-by-step tutorial, we’ll cover:
✔ Preparing two datasets
✔ Creating a scatter plot
✔ Editing and customizing the plot
✔ Using secondary axes and adjusting axis scales
✔ Saving your chart as a picture

Let’s dive in! 🚀

🟢 Step 1: Prepare Your Data

For two datasets, arrange them side by side.

Example: Comparing Two Products’ Sales

Month	Product A Sales	Product B Sales
1	500	50
2	1000	120
3	1500	200
4	2000	350
5	3000	600

👉 Notice that Product A sales are much larger than Product B sales — this is where a secondary axis will be useful.

🟢 Step 2: Insert the Scatter Plot

Highlight your data (all three columns).
Go to the Insert tab → Charts group → Scatter (X, Y).
Select Scatter with only Markers.

✅ Now, Excel will plot two series (Product A and Product B) against Month.

🟢 Step 3: Add Chart Elements

Select the chart → Click Chart Elements (+).
Add:
- Chart Title → “Comparison of Product A & B Sales Over Time”
- Axis Titles →
  - X-axis = Months
  - Y-axis = Sales (Units)
- Legend → To differentiate Product A and B.

🟢 Step 4: Insert a Secondary Axis

Since Product A sales are much higher, Product B might look too flat. Let’s fix that:

Right-click on Product B data points → Format Data Series.
In the Format pane → Check Plot Series on Secondary Axis.

✅ Now you’ll see two Y-axes:

Left axis → Product A Sales
Right axis → Product B Sales

This makes it easy to compare two datasets of different magnitudes.

🟢 Step 5: Scale the Axes

To improve clarity, adjust axis ranges manually:

For X-axis (Months):

Right-click X-axis → Format Axis.
Set:
- Minimum = 0
- Maximum = 6
- Major Unit = 1

For Y-axis (Primary - Product A):

Right-click left Y-axis → Format Axis.
Set:
- Minimum = 0
- Maximum = 3500
- Major Unit = 500

For Secondary Y-axis (Product B):

Right-click right Y-axis → Format Axis.
Set:
- Minimum = 0
- Maximum = 700
- Major Unit = 100

👉 This way, both datasets are properly scaled and easy to compare.

🟢 Step 6: Customize Markers and Add Trendlines

Change Marker Style

Product A → Blue circles, size 10
Product B → Red squares, size 10

Add Trendlines

Right-click on Product A → Add Trendline → Linear.
Repeat for Product B.
Check Display Equation on chart and R² value for analysis.

🟢 Step 7: Final Touches

Background: Right-click chart area → Format → Choose subtle color.
Legend: Place below chart for a clean look.
Data Labels (Optional): Right-click → Add Data Labels → Adjust position.

🟢 Step 8: Save Chart as a Picture

Click on the chart → Right-click → Save as Picture.
Choose format:
- PNG (best for blogs/web)
- JPEG (smaller size)
- SVG (scalable, for presentations)
Save to your desired folder.

✅ Now you can insert the chart into documents, reports, or blog posts!

🟢 Example: Final Scatter Plot Features

Your final chart should have:

Two datasets with different markers
Secondary axis for fair comparison
Customized scales for clarity
Trendlines with equations
A professional title, labels, and legend
Exported as a high-quality image

🔑 Key Takeaways

Scatter plots are best for showing relationships between two variables.
When datasets have different scales, use a secondary axis.
Always adjust axis scaling to make patterns visible.
Save your chart as an image for easy use in reports, slides, and blogs.

FUN PROJECT : Turn Your storage device (or Cloud Storage) into an Auto Shutdown Switch for Your PC

Ever wondered if you could use a file on your hard disk—or even a file stored online—as a “key” to keep your PC running, and automatically shut it down if that key disappears or changes? With a few lines of Python, you can do just that! This project demonstrates how to create an auto shutdown switch using a simple text file.

🔹 Project Overview

This Python script monitors a specific file on your system. If the file is missing or its content is not exactly "run", the script will immediately shut down your computer. You can place this script in your Startup folder so that it runs every time your PC starts.

This is useful for scenarios like:

Making sure your system only runs when a specific storage device is connected.
Creating a safety switch for shared computers.
Remotely controlling shutdowns via an online repository.

🔹 The Code


import os
import sys

# 🔧 Change this to your external storage file path
file_path = "E:\\shutdownpc\\shutdownpc.txt"   # Example path, update as needed

def shutdown():
    if os.name == "nt":  # Windows
        os.system("shutdown /s /t 1")
    elif os.name == "posix":  # Linux / macOS
        os.system("shutdown now")
    sys.exit()

def check_file_once():
    if not os.path.exists(file_path):
        shutdown()
    else:
        with open(file_path, "r") as f:
            content = f.read().strip().lower()
            if content != "run":
                shutdown()

if __name__ == "__main__":
    check_file_once()

🔹 How the Code Works

Set the file path
The variable file_path should point to the text file you want to use as your “key.” This can be a file on a USB drive, an external hard disk, or even a folder synced with cloud storage.
Shutdown function
The shutdown() function detects your operating system. On Windows, it executes the shutdown /s /t 1 command to shut down immediately. On Linux or macOS, it runs shutdown now. After issuing the shutdown command, the script exits.
Check file once
- check_file_once() first checks if the file exists. If it doesn’t, the shutdown is triggered.
- If the file exists, it reads the content. If the content is not "run" (case-insensitive), it triggers shutdown.
Run on startup
By placing this script in your Startup folder, your system will check the file automatically whenever it boots up.

🔹 Extending to Remote Shutdown

You don’t have to rely on a physical hard disk. Any online repository (like Google Drive, Dropbox, or even a GitHub file) can act as the shutdown trigger. You just need to:

Use a Python library such as requests to fetch the file content from the web.
Check if the content equals "run".
Trigger the shutdown if the file is missing or modified.

This opens up exciting possibilities for remotely controlling your laptop or server
