20-Apr-2023In Python, a for loop is a control flow statement used to iterate over a sequence of values. It is a type of loop that repeats a set of instructions for a specified number of times or until a certain condition is met.
For example, let's say we have a list of numbers numbers = [1, 2, 3, 4, 5] and we want to print each number in the list. We can use a for loop to iterate over the list and print each element as follows:
In this example, the for loop iterates over the numbers list and assigns each element to the variable number. The print(number) statement is then executed for each element in the list, printing the value of number on a new line.

30-Mar-2023A for loop in Python is a type of loop that enables you to iterate over a sequence of elements, like a string or a list, and execute a block of code for each element in the sequence. During each iteration of the loop, the value of the variable changes to the next element in the sequence. The syntax of a for loop includes the variable and sequence that will be iterated over and the code block that will be executed for each iteration. The sequence can be any iterable object such as a list, tuple, string, or range object.
Syntax:
Here, the var is a variable that takes on the value of each item in the sequence, one at a time. The statement(s) inside the loop is executed once for each value of var.
Example:
In this example, the numbers list contains the values 1 through 5. The for loop iterates over each value in the list, and the num variable takes on the value of each item in turn. Inside the loop, the current value of num is printed using the print() function.
The for loop is a powerful construct that can be used to process data, manipulate strings, and iterate over complex data structures such as dictionaries and sets.
