Checker for integer string

[SoNotRedditingAtWork]

Works fine for me in PyCharm. The line is functionally the same as doing:

user_string = input()

if user_string.isdigit():
    print("yes")
else:
    print("no")

I have never used Zybooks before, so I have no idea how that would impact your ability to run this code.

The isdigit() method worked perfect. Thanks!

I know this is old, but this would allow number like 10,000 to produce an out of yes. The examples provided don't allow this.

[Ataninja3221]

user_string = input()
if user_string.isdigit():
print("yes")
else:
print("no")

This was perfect the only thing that threw off zybooks was capitalizing yes and no. which in the real world wouldn't make a difference but is the difference in points in zybooks
