I am trying to debug a script which takes command line arguments as an input. Arguments are text files in the same directory. Script gets file names from sys.argv list. My problem is I cannot launch the script with arguments in pycharm.

I have tried to enter arguments into "Script parameters" field in "Run" > "Edit configuration" menu like so:

-s'file1.txt', -s'file2.txt'

But it did not work. How do I launch my script with arguments?

P.S. I am on Ubuntu

In PyCharm the parameters are added in the Script Parameters as you did but, they are enclosed in double quotes "" and without specifying the Interpreter flags like -s. Those flags are specified in the Interpreter options box.

Script Parameters box contents: 

"file1.txt" "file2.txt"

Interpeter flags:

-s

Or, visually:

Then, with a simple test file to evaluate:

if __name__ == "__main__":
    import sys
    print(sys.argv)

We get the parameters we provided (with sys.argv[0] holding the script name of course):

['/Path/to/current/folder/test.py', 'file1.txt', 'file2.txt']
