Cannot import Decimal module

Question

I am trying to do some simple decimal math to practice with the Tkinter GUI, but for some reason I cannot import Decimal:

>>> from decimal import Decima         


        

Answer 1

You called a file math.py, meaning it overrides the built-in math module and breaks everything that uses that module. Pick a different name, and the problem will go away.

Answer 2

I was having the same issue of Python 3+ not being able to import Decimal. Even some external libraries, like pygal, would not install because the system could not access Decimal and decimal library.

I found accidentally in another site that "there maybe another decimal.py file in your system, shadowing on the decimal library".

I checked and found out that I had named a test file (while I was learning Python) as decimal.py and after I renamed this to decimaltest.py everything is working perfect.

Check if you have done the same or you have any similar wrongly named file in your system.
