I did my research on winreg and I found out that it is a Windows Register. Am I getting this error because I am using a Mac? I have python 3.8.2 on my system.
Help.

Cannot import name StringIO when importing dateutil

I'm having a 'Cannot import name StringIO' error message when importing dateutil which tries to import StringIO but cannot find it. Here is complete trace:
(DEV)arbi#el-oued:~/Work/sentimentpy$ python core/main.py
Traceback (most recent call last):
File "core/main.py", line 7, in <module>
from io.reader import *

from io import StringIO
ImportError: cannot import name StringIO
When I tried to use python3 to launch my program, i had this error:
(DEV)arbi#el-oued:~/Work/sentimentpy$ python3 core/main.py
Traceback (most recent call last):

from numpy
ImportError: No module named numpy
Why I'm having this? i've installed numpy in my virtualenv with: pip install numpy

You are masking the built-in io module because you have a package named io in your project:
Traceback (most recent call last):
File "core/main.py", line 7, in <module>
from io.reader import *
File "/home/arbi/Work/sentimentpy/core/io/reader.py", line 4, in <module>
The line from io import StringIO finds /home/arbi/Work/sentimentpy/core/io, not the built-in module.
Rename that package or move it into a new top-level package name that doesn't conflict.
Your second error is unrelated; you simply don't have numpy installed for Python 3.
