Explain For loops in Python?

Programming Language
#1

Loops are used in programming to repeat a specific block of code. A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).

This is less like the for keyword in other programming languages, and works more like an iterator method as found in other object-orientated programming languages. With the for loop we can execute a set of statements, once for each item in a list, tuple, set etc.

Syntax:

for val in sequence:
    loop body

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:

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)

Output:

The sum is 48
