Error: No module named 'pymem.process'; 'pymem' is not a package

I am trying to learn how to use pymem in Python.
I have tried to make two different programs according to two tutorials I have seen but I always get the same error when I try to run the code.
I have this:
from pymem import Pymem
pm = pymem("ac_client.exe")
health = pm.read_int(0x007B43F4)
print ("Health: ", health)
But when I try to run the code I get the following error:
Traceback (most recent call last):
File "c:\Users\N\Desktop\PYTHON\pymem\pymem2.py", line 1, in <module>
from pymem import Pymem
File "c:\Users\N\Desktop\PYTHON\pymem\pymem.py", line 4, in <module>
from pymem.process import *
ModuleNotFoundError: No module named 'pymem.process'; 'pymem' is not a package
I have pymem installed in it's latest version from Visual Studio Code. And in the videos I've seen (one is from a few months ago) they have the same code as me.

You have a file named pymem.py that's mentioned in the exception message (specifically c:\Users\N\Desktop\PYTHON\pymem\pymem.py). This locally written pymem module is shadowing the pymem package you've installed elsewhere (python\python310\lib\site-packages according to one of your comments, though that path is not complete).
You need to rename your pymem.py file to something else if you want to be able to use the package.

I think you don't have it installed, try going into cmd, Terminal or whatever and type pip install pymem.
pip should install the package for you and you should be good.

Errors importing pyodbc

My background is Java/C++ and I'm very new to python. I'm trying to import pyodbc to my project which works alright if I do it via command line.
import odbc
However, when I try to do the same in pydev/eclipse, i get the following error which I cannot find a solution to. I suspect this may have something to do with Eclipse setup
Traceback (most recent call last):
File "C:\Users\a\workspace\TestPyProject\src\helloworld.py", line 2, in <module>
import pyodbc
File "C:\Users\a\AppData\Local\Continuum\Anaconda3\Lib\site-packages\sqlalchemy\dialects\mssql\pyodbc.py", line 105, in <module>
from .base import MSExecutionContext, MSDialect, VARBINARY
ImportError: attempted relative import with no known parent package
I'm really stuck here and any hints will be appreciated!

An incorrect library was imported into the External Libraries list of the project. After fixing it, the import is working.

Import error in Python: Polygon

I installed this library called Polygon, in Python 2.7.3. But, each time I import it I get the next error message :
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "Polygon/__init__.py", line 5, in <module>
from Polygon.cPolygon import *
ImportError: No module named cPolygon
I have no idea about what could be going wrong. And also, I have already tried to contact the original author of this on his personal webpage.
but he hasn't replied though :( I wonder if someone can help me with this issue please.

It sounds like you didn't in fact install it, but instead just copied it to your working directory. As always, run setup.py with the appropriate arguments to install.

This error can happen if you try to run python from inside the directory you used to install Polygon. Move to a different directory and try again.

Netbeans + sqlite3 = Fail?

I've decided to give Python a try on Netbeans. The problem so far is when try to run program I know works, i.e. if I ran it through the terminal. For the project I selected the correct Python version (2.6.5). And received the following error:
Traceback (most recent call last): File
"/Users/XXX/NetBeansProjects/NewPythonProject3/src/newpythonproject3.py",
line 4, in
import sqlite3 ImportError: No module named sqlite3

Search for PYTHONPATH. You probably have different settings in your OS and Netbeans.

Why am I getting the following error in Python "ImportError: No module named py"?

I'm a Python newbie, so bear with me :)
I created a file called test.py with the contents as follows:
test.py
import sys
print sys.platform
print 2 ** 100
I then ran import test.py file in the interpreter to follow an example in my book.
When I do this, I get the output with the import error on the end.

Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: No module named py
Why do I get this error and how do I fix it? Thanks!

Instead of:
import test.py
simply write:
import test
This assumes test.py is in the same directory as the file that imports it.

This strange-looking error is a result of how Python imports modules.
Python sees:
import test.py
Python thinks (simplified a bit):
import module test.
search for a test.py in the module search paths
execute test.py (where you get your output)
import 'test' as name into current namespace
import test.py
search for file test/py.py
throw ImportError (no module named 'py') found.
Because python allows dotted module names, it just thinks you have a submodule named py within the test module, and tried to find that. It has no idea you're attempting to import a file.

You don't specify the extension when importing. Just do:
import test

As others have mentioned, you don't need to put the file extension in your import statement. Recommended reading is the Modules section of the Python Tutorial.
For a little more background into the error, the interpreter thinks you're trying to import a module named py from inside the test package, since the dot indicates encapsulation. Because no such module exists (and test isn't even a package!), it raises that error.
As indicated in the more in-depth documentation on the import statement it still executes all the statements in the test module before attempting to import the py module, which is why you get the values printed out.
