Hi ... I am wondering why this code is not working

for number in range(20,30):

`if number.is_prime():`

   `print number`

I got this error in Cocalc Error in lines 1-3 Traceback (most recent call last): File "/cocalc/lib/python2.7/site-packages/smc_sagews/sage_server.py", line 1013, in execute exec compile(block+'\n', '', 'single') in namespace, locals File "", line 2, in <module> AttributeError: 'int' object has no attribute 'is_prime'

However, it works when I change the code to

for number in range(20,30):
    if is_prime(number):
        print number
