ModuleNotFoundError: No module named 'folium.plugins'; 'folium' is not a package [duplicate]

This question already has answers here:
Importing installed package from script with the same name raises "AttributeError: module has no attribute" or an ImportError or NameError
(2 answers)
Closed 4 years ago.
I know this question has been asked around quite a few times but none of the solutions have helped me out so far.
I am getting the following error whenever I try running my python script:
M-MBP:folder m$ python3.7 folium.py
Traceback (most recent call last):
File "folium.py", line 3, in <module>
import folium
File "/Users/m/folder/folium.py", line 4, in <module>
from folium.plugins import MarkerCluster
ModuleNotFoundError: No module named 'folium.plugins'; 'folium' is not a package
Notes:
I am running Python3.7, installed via Homebrew;
I've tried installing Folium via pip, conda, and cloning its Git repo directly to my site-packages folder.
None have worked. Any suggestions?
Thanks!
Your script is named the same as the package you want. It's trying to import itself and it doesn't have plugins within it. Name your script something other than folium.py and I believe your problem will disappear.

In this second chunk, you'll see that I deleted the first chunk of the list. This removes your CURRENT DIRECTORY from python's import path, so it now ignored my logging.py file and successfully imported the real logging module.

python3 does not allow urllib import

I installed anaconda for Python 3.6 in MacOs Sierra.
It comes with its own python and it changed the default python to this new one.
Now, I am not able to import anything from urllib.
Here is a snippet of my terminal.
Can someone give some suggestions?

Why does python -c "..." load different dateutil than python file.py

Why would this work:
$ python -c "import dateutil; print dateutil.__version__"
2.6.0
but this would fail on, test.py:
import dateutil; print dateutil.__version__
when run as
$ python test.py
Traceback (most recent call last):
File "test.py ", line 3, in <module>
import dateutil; print dateutil.__version__
AttributeError: 'module' object has no attribute '__version__'
The same python interpreter, same bash session and environment is used for both:

It turns out I had a dateutil.py file in the same directory. :-(
And . in my PYTHONPATH :-( :-(

ImportError: No module named log

Isn't log a built in package in python?

Do I need to install log with pip ?
logging is a built-in package, not log:

Python on Ubuntu: 'module' object has no attribute 'c_bool'

How can I fix this problem?
Do you have a file called "ctypes.py" in the directory where you are working? If so, move it or (preferably) rename it.
