In this article, you’ll learn to iterate over a sequence of elements using the different variations of for loop.
What is for loop in Python?
The for loop in Python is used to iterate over a sequence (list, tuple, string) or other iterable objects. Iterating over a sequence is called traversal.
Syntax of for Loop
for val in sequence: Body of for
val is the variable that takes the value of the item inside the sequence on each iteration.
Loop continues until we reach the last item in the sequence. The body of for loop is separated from the rest of the code using indentation.
Example: Python for Loop
# Program to find the sum of all numbers stored in a list # List of numbers numbers = [6, 5, 3, 8, 4, 2, 5, 4, 11] # variable to store the sum sum = 0 # iterate over the list for val in numbers: sum = sum+val print("The sum is", sum)
when you run the program, the output will be:
The sum is 48
