Python Practice (vii) calculates the and of the factorial of 1 to N

Factorial:

All the product of a positive integer less than and equal to the number, when n is 5 o'clock, the factorial of 5 is 5!=1*2*3*4*5=120

The factorial of 0 is always equal to 1.

The factorial of 1 equals 1*1 1.

The factorial of 2 equals 1*1*2 2.

The factorial of 3 equals 1*1*2*3 6.

The factorial of 4 equals 1*1*2*3*4 24.

The factorial of 5 equals 1*1*2*3*4*5 120.

For example, calculate the factorial of 5 with the following code:

n = 5sum = 1for i in range (1, n + 1): Sum *= iprint (sum)

Calculate the factorial of 1 to 5 and the code is as follows:

n = 5sum = 1total = 0for i in range (1, n+1): #1, 2,3,4,5 sum *= i total + = Sumprint

Control of the value boundary of n

Sum represents the value of the factorial of each number

Sum of total totals
