Exception: AttributeError: module 'random' has no attribute

• A common mistake. Using the wrong filename.

This works fine:

print("Hello World")

This gives an error

import random
print(random.random())

Traceback (most recent call last):
  File "rnd.py", line 2, in <module>
    print(random.random())
AttributeError: module 'random' has no attribute 'random'
