Скачать или смотреть Python List Comprehension (Clean & Fast Code) | [DAY-15] – Python Basic to Advanced (AI/ML) in Hindi

In Day 15, we learn one of the most loved Python features — List Comprehension.
What you'll learn in this lesson:
What list comprehension is and why it exists
Converting traditional for loops into one-line expressions
Filtering items using conditions
Using lower() for case-insensitive checks
Creating lists from range()
General syntax:
[expression for item in iterable if condition]
Writing clean, readable, and efficient Python code
List comprehension isn't just a shortcut — it's a mindset.

=======================HOME ASSIGNMENT=======================

1️⃣ Filter Practice (Warm-up)
Create a list of words:
words = ["Python", "Java", "C", "Javascript", "Go"]
Using list comprehension, create a new list that contains:
only words with length greater than 3
Print the new list.

2️⃣ Number Generator
Using list comprehension:
create a list of numbers from 1 to 20
create another list containing only even numbers
No loops allowed. If there’s a for block, redo it 😄

3️⃣ Uppercase Converter
Given:
names = ["karan", "rohit", "mohan"]
Create a new list where:
all names are converted to uppercase
Print both original and new list to show difference.

4️⃣ Replace Logic (Think Mode 🔥)
Given:
fruits = ["Apple", "Banana", "Apple", "Cherry"]
Create a new list where:
"Apple" is replaced with "Orange"
other items stay the same
👉 Hint: use conditional expression inside list comprehension.

5️⃣ Mini Project: Clean Data Filter 🧹
Given:
raw_data = ["Python", "", "Java", "", "C++", ""]
Using list comprehension:
create a list that removes empty strings
print cleaned data
This feels like real-world data cleaning (because it is).

🔥 Bonus (Optional but Cool)
Create a list:
nums = [1, 2, 3, 4, 5]
Using list comprehension, create:
a new list of squares
