How do I modify program files in Python?

Question

In the actual window where I right code is there a way to insert part of the code into everyline that I already have. Like insert a comma into all lines at the first spot>?

Answer 1

Code is data. You could do this like you would with any other text file. Open the file, read the line, stick a comma on the front of it, then write it back to file.

Also, most modern IDEs/text editors have the ability to define macros. You could post a question asking for specific help for your editor. For example, in Emacs I would use C-x ( to start defining a macro, then ',' to write a comma, then C-b C-n to go back a character and down a line, then C-x ) to end my macro. I could then run this macro with C-x e, pressing e to execute it an additional time.
