python 3.5 : quit a if loop (or other loops)

When ruing the program, the user is asked to input a number. If the number is 1, quit the program. If the number is not 1, print the number.

I wonder how to realize this.

I am using python 3.5.

My code is like this. I always get an error: 'break' outside loop

How can I fix this?

x = input('Please input a number: ')
if x == '1':
    print('quit')
    break
else:
    continue
print(x)
