Why this change?
| print(f"data={str(data)}") | |
| print(f"{data = }") |

This and similar changes are redundant as string interpolation converts the object to string using the __str__ method of the object.

I'm not sure why but without it we get the following mypy-errors:
file_transfer/send_file.py:16: error: On Python 3 '{}'.format(b'abc') produces "b'abc'", not 'abc'; use '{!r}'.format(b'abc') if this is desired behavior
file_transfer/receive_file.py:16: error: On Python 3 '{}'.format(b'abc') produces "b'abc'", not 'abc'; use '{!r}'.format(b'abc') if this is desired behavior

I guess it has something to do with the method from the socket-package that returns the data-object.

bytes vs. str is the most time-consuming part of porting code from Python 2 to Python 3.
% python3
>>> type(b"abc")
<class 'bytes'>
>>> type("abc")
<class 'str'>

@dhruvmanila Do we need these imports for basic types in Python 3.9 and the current mypy?

I see, I made the corresponding changes. One difference is that the basic types are spelled lower case without this import.
This reverts commit 2f7c473.

Describe your change:
Related Issue: #4052
comment for strassen_matrix_multiplication.py: I couldn't use Tuple as return type since one branch of the function returns a tuple an another a list/matrix. So I turned the tuple into a list instead.
comment for electric_power.py & ohms_law.py: I added a final else-clause for raising an error to make sure that each branch either has a return-value or throws an error
