After deliberating about this question here it looks like something is wrong with my command prompt.
Even the file called test.py
containing the following code
print("hi")
doesn't lead to any output being shown when called in my command prompt on windows 10
Output
C:\Users\Admin>python test.py
C:\Users\Admin>
Meaning nothing is printed.
As suggested in my original question I also tried running
python -u -c "print('hello')"
Which doesn't yield any output neither.
There is already a question concerned with the same problem, however doesn't have any answers yet.
