A for loop in Python is used to iterate over a sequence (like a list, tuple, dictionary, set, or string). Here’s how it works:

• You can create a for loop using the syntax: `for item in sequence:`.
• The loop executes a block of code for each item in the sequence.
• For example, to print each element in a list:```pythonmy_list = [1, 2, 3]for item in my_list:print(item)```
• For loops are particularly useful when you know the number of iterations in advance or when working with iterable objects.

For more detailed information, you can refer to the.

• Definition: A `for` loop is used to iterate over a sequence (like a list, tuple, string, or range) and execute a block of code for each item in that sequence.
• Usage: It is ideal when you know the number of iterations in advance. For example, to print each item in a list:```pythonfruits = ["apple", "banana", "orange"]for fruit in fruits:print(f"I love eating {fruit}s!")```
• Key Point: The loop automatically takes each item from the sequence and assigns it to a variable, executing the indented code block for each item.

• Definition: A `while` loop repeatedly executes a block of code as long as a specified condition is `True`. Once the condition evaluates to `False`, the loop stops executing.
• Usage: It is useful when the number of iterations is not known beforehand and depends on a condition. For example, to print numbers from 1 to 5:```pythoni = 1while i <= 5:print(i)i += 1```
• Key Point: Care must be taken to ensure that the condition will eventually become `False`, or the loop may run indefinitely.

• For Loop: Best for iterating over a known sequence or range.
• While Loop: Best for situations where the number of iterations is determined by a condition rather than a fixed sequence.These loops are fundamental constructs in Python that help automate repetitive tasks, making code more efficient and easier to manage. Understanding how to use them effectively is crucial for any Python programmer.
