Hi there,
This is a beginner question.
I learned that
with open("foo.txt") as f:
lines = f.readlines()
using the with-construct is the recommended way to deal with files
making sure that close() always happens.
However, I also could do:
lines = open("foo.txt").readlines()
I have to

Hi there,
More often I see something like this:
class Myclass:
...
but sometimes I see
class Myclass(object):

Question: which way is preferable?

Hi there,
Pretty new to python I've got a question regarding the proper shebang
for Python 3.
I use
#!/usr/bin/python3
which works fine.
Today I saw
#!/usr/bin/python3 -tt
and was wondering what -tt means.
Being on Fedora 30, Python 3.7.3 the man page of python3 doesn't even
mention

I think that per definition a path in a shebang has to be absolute.

I had a look into type checking and tried a very simple example like
the following:
#!/usr/bin/env python3
def greeting(name: str) -> str:
return 'Hello ' + name
def main():
print(greeting(1))
if __name__ == "__main__":
main()
pytype complained as expected.
BUT mypy says;

I unzip a zip file like follows which works fine.
with ZipFile(zip_file, 'r') as zip:
zip.extractall(tmp_dir)
The only caveat is that the unpacked files and dirs do have a current
timestamp i.e. the timestamps of the files are not preserved.
Is there a way to tell ZipFile to

Hi there,
I am asking myself if I should preferably use single or double quotes
for strings?
If I need a single quote in a string I would use double quotes for the
whole string and vice versa. For f-strings I mostly see double
quotes but single quotes would work as well I think.

- if isinstance(v, int)

I have a situation where in a directory tree I want to change a certain

My idea was to do
- os.scandir and for each file
- check if a file is a text file
- if it is not a text file skip that file
- change the string as often as it occurs in

Let us say I have a package which reads a TOML file.
I want to give the user of my package the choice to decide if he wants
to use the toml, tomlkit or rtoml package.
So, in case the user chose to use rtoml then there should be an import
only for rtoml, aso.
How could I achieve this?

The are many possibilities to package a Python app, and I have to admit
I am pretty confused.
Here is what I have:
A Python command line app which requires some packages which are not in
the standard library.
I am on Linux and like to have an executable (perhaps a zip file with a
