Running patch within a function

Question

I need to make some changes to an xml using a 'patch.txt' file, generated with diff, within a function.

I am able to do this on the command line with:

patch export.xml patch.txt 

but when I use

subprocess.run(["patch" "export.xml patch.txt"]) 

within a function, this process is not called.

Any ideas on how to perform patching within python code?

Answer 1

Space is the separator for the shell input. So the code should be:

subprocess.run(["patch", "export.xml", "patch.txt"])
