For Loop in Python

The for loop in Python is a control flow statement used to iterate over a sequence (like lists, tuples, dictionaries, sets, or strings) or any other iterable object. It is versatile and allows efficient traversal through elements in a sequence.

Key Points on For Loop:

• The for loop is typically used when the number of iterations is known or the structure is iterable.
• It automatically ends when it reaches the end of the sequence or iterable.
• Commonly used with the range() function to generate sequences of numbers.
• Nested for loops allow more complex data structures to be handled.
• Control statements like break and continue can be used to manage the flow.

Syntax of For Loop:

for element in iterable:
            # Code to execute for each element

Example of For Loop in Python:

This example demonstrates a basic for loop that iterates over a list of numbers and prints each number.

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

Detailed Explanation:

• Iterable: The sequence or object to loop over, such as a list or a range of numbers.
• Loop Variable: The variable (like number above) that represents each element in the iteration.
• Range: The range() function is often used to generate a sequence of numbers, especially in loops.
• Nested For Loops: Useful for multi-dimensional data structures, such as lists of lists.

Using the for loop effectively enables efficient data handling and iteration in Python programs.
