Pycharm and sys.argv arguments

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']

For the sake of others who are wondering on how to get to this window. Here's how:

You can access this by clicking on Select Run/Debug Configurations (to the left of ) and going to the Edit Configurations. A gif provided for clarity.

On PyCharm Community or Professional Edition 2019.1+ :

1. From the menu bar click Run -> Edit Configurations
2. Add your arguments in the Parameters textbox (for example file2.txt file3.txt, or --myFlag myArg --anotherFlag mySecondArg)
3. Click Apply
4. Click OK

In addition to Jim's answer (sorry not enough rep points to make a comment), just wanted to point out that the arguments specified in PyCharm do not have special characters escaped, unlike what you would do on the command line. So, whereas on the command line you'd do:

python mediadb.py  /media/paul/New\ Volume/Users/paul/Documents/spinmaster/\*.png

the PyCharm parameter would be:

"/media/paul/New Volume/Users/paul/Documents/spinmaster/*.png"
