Python Loops

Python provides several types of loops for executing a block of code repeatedly. The most commonly used loop structures in Python are the for loop and the while loop. Let me explain each of them:

For loop:

A for loop is used to iterate over a sequence (such as a list, tuple, string, or range) or any other iterable object. It executes a block of code a fixed number of times, once for each item in the sequence. Here’s the general syntax of a for loop in Python:

for item in sequence: 
    #Code block to be executed

Here’s an example that prints each item in a list:

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

Output:

apple
banana
cherry

While loop:

A while loop is used to repeatedly execute a block of code as long as a given condition is true. It is useful when you want to continue executing the code until a certain condition is met. Here’s the general syntax of a while loop in Python:

while condition: 
    # Code block to be executed

Here’s an example that prints numbers from 1 to 5 using a while loop:

count = 1
while count <= 5:
    print(count)
    count += 1

Output:

1
2
3
4
5

These are the basic loop structures in Python.
