Python program to find the factors of a number

Python example大全

In this program, you will learn to use a for loop to find the factors of a number.

To understand this example, you should understand the followingPython programmingTopic:

• Python if ... else statement

• Python for loop

• Python user-defined function

Source code

# Use Python program to find a number's factors
# This function calculates the factors of the passed parameter
def print_factors(x):
　　　print(x, "has factors:")
　　　for i in range(1, x　+　1)
　　　　　　　if x % i == 0:
　　　　　　　　　　　print(i)
num =　320
print_factors(num)

Output result

32The factors of 0 are:
1
2
4
5
8
10
16
20
32
40
64
80
160
320

Note:To find the factors of another number, change the value of num.

In this program, the number whose factors are found is stored in num, which is passed to the print_factors() function. This value is assigned to the variable x in print_factors().

In this function, we use a for loop to iterate from i equals x, if x is completely divisible by i, it is a factor of x.
