Loop for interpret the python script (.py) - unix

Question

I'm a beginner for Python. My question might be basic, but I cannot figure it out. What I want to do is to run the following command 100 times in which the variable "num" runs from 0 through 99.
python test.py input_num.txt -i 5 --cor_file=output_num.txt
For example:
python test.py input_0.txt -i 5 --cor_file=output_0.txt
python test.py input_1.txt -i 5 --cor_file=output_1.txt
...
:::
python test.py input_99.txt -i 5 --cor_file=output_99.txt
I know that I have to write a script for running the loop, but cannot figure it out yet. If you have any recommendation, that would be very nice.
I tried to write a script called main.py containing the following commands, but it didn't work.
#!/usr/bin/env python
import test
ext_str = '.txt'
inp = 'input_'
out = 'output_'
for num in range(0,99):
inp += 'num'
inp_str = inp + ext_str
out += 'num'
out_str = out + ext_str
python test.py inp_str -i 5 --cor_file=out_str
Thank you very much.
Best,
Pim

In your case you need to call the python interpreter on various files, e.g. you need to call the "python" shell command, it means that you have to create a shell script (and not a python script, actually you could do it with some python code but it would be way too complicated in your case):
for i in {0..99}
do
python test.py input_$i.txt -i 5 --cor_file=output_$i.txt
done
put the above code in a ".sh" file then don't forget to "chmod +x the ", then run it with ./.sh (given that your are in the current directory).
