Why this comand is not working?

Question

numbers = list(range(5, 20, 2))
Traceback (most recent call last):
File "<pyshell#114>", line 1, in <module>
numbers = list(range(5, 20, 2))
TypeError: 'int' object is not callable

Answer 1

I tried it and it worked without any problems. If the error message says that something is "not callable" that might be a hint that parentheses were used incorrectly:

a = 5 # a is an integer
a() # trying to call an int object like a function

=> TypeError: 'int' object is not callable

Answer 2

I agree with Anna, I don't see any issue with that line. Could it be that you used list or range as a variable earlier? Something like this can cause it:

range = 200
numbers = list(range(5, 20, 2))
