For Loop in Python

 A for loop in Python is a control flow statement that allows you to iterate over a sequence (e.g., list, tuple, dictionary, string, range) and execute a block of code for each item in the sequence. The basic syntax of a for loop in Python is:

yaml
for item in sequence: # code block to be executed for each item in the sequence

Here, item represents the current item in the sequence being iterated, and sequence represents the iterable object (e.g., list, tuple, etc.) over which you are iterating.

For example, let's say you have a list of numbers and you want to print each number on a new line. You can use a for loop to iterate over the list and print each item:

css
numbers = [1, 2, 3, 4, 5] for number in numbers: print(number)

This will output:

1 2 3 4 5

You can also use the range() function to generate a sequence of numbers and iterate over it using a for loop:

scss
for i in range(5): print(i)

This will output:

0 1 2 3 4

You can combine a for loop with conditional statements (if-else statements) to perform certain actions based on certain conditions
