Hi Python Team,
I think the statement "The __init__.py files are required to make Python
treat directories containing the file as packages" is wrong in the
documentation[1] because it is valid only for Python 2.x version not Python
3.x version.
Even though it is good practice to have this file, it

Dear all,
I have the following question regarding how to scrape Google Map to get
address based on a given list of geocodes.
Given a list of geocodes (latitude; longitude) of locations, I would like
to scrape municipalities of all the spots in the list. How can I do that?
For example, I have

Hello, forum,
I have a data frame with covid-19 cases per month from 2019 - 2021 like a
header like this:
Country, 01/01/2019, 2/01/2019, 01/02/2019, 3/01/2019, ... 01/01/2021,
2/01/2021, 01/02/2021, 3/01/2021
I want to filter my data frame for columns of a specific month range of march
to Sep
How about this?:
python3 -c 'list_ = [1, 3, 5, 4, 2]; am = max((value, index) for index,
value in enumerate(list_)); print(am)'

Sometimes I like to pass the logging level up to the command line params so my
user can specific what level of logging they want. However there is no easy
method for pulling the named logging level names.
Looking into the code, it would actually be incredibly easy to implement;
