The factorial of a non-negative integer n is the product of all positive integers less than or equal to n. For example, if n is 5, the return value should be 120 because 1*2*3*4*5 is 120. Check Code Video: Python for Loop Previous Tutorial: Python if...else Statement Next ...

Using the Python for Loop with a Range The Python for statement is frequently used with the range keyword. When the range function is used to calculate the sequence, the loop keeps running as long as the iterator falls within the range. When used with the range function, the syntax for a...
2. Find factorial using RecursionTo find the factorial, fact() function is written in the program. This function will take number (num) as an argument and return the factorial of the number.# function to calculate the factorial def fact(n): if n == 0: return 1 return n * fact(n -...
Python for loop program: Here, we are going to implement a program that will demonstrate examples/use of for loop.

You can also use some functions from the math module like sqrt(), factorial(), sin(), cos(), and so on. Here’s an example using factorial(): Python >>> import math >>> numbers = [1, 2, 3, 4, 5, 6, 7] >>> list(map(math.factorial, numbers)) [1, 2, 6, 24, 120...
