For loop and while loop in python

For Loop in Python: Iterating Through Sequences

The `for` loop in Python is used to **iterate through sequences** like lists, tuples, strings, and ranges. It helps automate repetitive tasks efficiently.

Why Use `for` Loops?

• Automates repetitive operations.
• Makes code cleaner and more readable.
• Works with different data structures.

Basic Syntax

fruits = ["apple", "banana", "cherry"]
for fruit in fruits:
    print(fruit)

Using `range()` in a For Loop

The `range()` function generates numbers for looping.

for num in range(1, 6):
    print(num)  # Output: 1, 2, 3, 4, 5

Looping Through a String

for letter in "Python":
    print(letter)

Conclusion

The `for` loop is a powerful tool for iterating through sequences effortlessly. How do you plan to use it in your projects?

While Loop in Python: Repeating Until a Condition is Met

The `while` loop in Python **executes code repeatedly as long as a condition remains true**. It’s ideal for situations where the number of iterations isn’t known beforehand.

Why Use `while` Loops?

• Runs until a condition is false.
• Useful for dynamic loops (e.g., user input).
• Perfect for event-driven logic.

Basic Syntax

count = 1
while count <= 5:
    print(count)
    count += 1  # Output: 1, 2, 3, 4, 5

Using a `while` Loop for User Input

password = ""
while password != "secret":
    password = input("Enter the password: ")
print("Access granted!")

Conclusion

The `while` loop is great for **handling dynamic conditions**. Where do you think it could be useful in your projects?
