Pycharm and sys.argv arguments

Question

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']

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.

Solution 3

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"

Notice that for some unknown reason, it is not possible to add command line arguments in the PyCharm Edu version. It can be only done in Professional and Community editions.

Thanks it worked. In addition it turns out that I should have used "" quotes instead of ''.

This was helpful; but to clarify, my python script takes two file names as parameters, one for -r and one for -s (or both or one or neither). So my script parameters were specified as [-p "prof_samples.txt" -r "resp_samples.txt"] with no interpreter options.

I think this answer is out of date because there is no script parameters

@tisaconundrum after checking with this, could you tell me what version of PyCharm you are running? I just downloaded the latest (PyCharm Community Edition 2017.2.3 Build #PC-172.3968.37, built on September 1, 2017) and still see the Script parameters option.

The short clip was actually helpful -- thank you! That's what I hate about gui things. Its like an Easter egg hunt whereas command line you just type it in.

After adding the parameter values, clicking APPLY or OK button not running the code. If I save the configurations and run the code, still arguments not considered in Pycharm python code

answer is outdated. for pycharm 2019.1.3 the field is just called Parametersand you don't have to put double quotes around your parameters.
