如何打印范围内的数字但排除给定可整除数字的数字

Question

I need to print out the range between 0-50 with the exclusion of numbers divisible by 7.

for x in range(0,50):#for loop range beginning 0-50
    if x % 7 == 0:
        print(x)

Answer 1

Just check if the number is divisible by using the modulo operator % .

The expression x % 7 will return the remainder of x divided by 7. If the remainder is not zero, then x is not divisible by 7, so print the number.

for x in range(0, 50):
    if x % 7 != 0:
        print(x)

Note that in Python, range(start, end) is [start, end); ie, your range includes every number from 0 to 49.
