In Python, a "for" loop is used to iterate (loop) over a sequence of elements, such as a list, tuple, string, or any other iterable object. It allows you to execute a block of code repeatedly for each item in the sequence.
The basic syntax of a for loop in Python is as follows:
__________________________________________________
for element in iterable:
# Code to be executed for each element
__________________________________________________
Here's a breakdown of how it works:
element is a variable that takes on the value of each item in the iterable one by one during each iteration of the loop.
iterable is any Python object that can be iterated over. It can be a list, tuple, string, dictionary, set, or any custom iterable object.
The indented block of code under the for statement is executed for each element in the iterable. This block of code is typically referred to as the loop body.
Here's an example of a for loop that iterates over a list of numbers and prints each number:
__________________________________________________
numbers = [1, 2, 3, 4, 5]
for num in numbers:
print(num)
__________________________________________________
In this example, the loop iterates over the numbers list, and during each iteration, the variable num takes on the value of the current element in the list. The print(num) statement then prints each number to the console.
You can use for loops to perform various tasks, including iterating through elements to perform calculations, searching for specific values, modifying elements, and more. They are a fundamental construct in Python for handling repetitive tasks.
