Why is this python code running twice [duplicate]

Question

Here is the code

import random

print("Hello", end="")
print("twice")

and a screenshot of the code

When I execute this code it for some reason is running twice. The problem seems to be from the import random statement, because if I either remove that statement or import some other module it works fine.

What could be the reason for this, should I reinstall Python on my system.

Answer 1

There's nothing wrong with python.

The reason is simple:

Your module is importing itself (because it is also named random) - this has to do with the lookup mechanics of python. python will try to import from your root folder first, before modules from pythonpath are imported.

From the docs:

When a module named spam is imported, the interpreter first searches for a built-in module with that name. If not found, it then searches for a file named spam.py in a list of directories given by the variable sys.path. sys.path is initialized from these locations:

• The directory containing the input script (or the current directory when no file is specified).
• PYTHONPATH (a list of directory names, with the same syntax as the shell variable PATH).
• The installation-dependent default.
