Report #40661

[bug\_fix] Importing a local script shadows a standard library module \(e.g., naming a file 'random.py' or 'json.py'\)

Rename your local file to avoid shadowing \(e.g., 'random\_demo.py' instead of 'random.py'\), remove any '.pyc' files and '\_\_pycache\_\_' directories, and restart the interpreter.

Journey Context:
You create a new script named 'random.py' to test random number generation. You write 'import random' and then 'print\(random.randint\(1,10\)\)'. You run it and get AttributeError: module 'random' has no attribute 'randint'. Confused, you check 'print\(random.\_\_file\_\_\)' and see it points to your current working directory's random.py, not the stdlib. You realize Python's sys.path puts the current directory first, so your local file shadows the standard library's random module. You also find a 'random.pyc' in \_\_pycache\_\_ that persists even after renaming. You rename the file to 'my\_random.py', remove \_\_pycache\_\_ and \*.pyc files, and the import now correctly resolves to the stdlib, fixing the AttributeError.
