Answer 1

Not in a situation to be able to test this so you may need to fiddle with the Regular Expression (they may be errors in it.)

import re
re.sub("SSViewer::set_theme\('[a-z]+'\)", "SSViewer::set_theme('whatever')", my_string)

Is this what you want?

Just tested it, this is some sample output:

my_string = """Some file with some other junk
SSViewer::set_theme('bullsorbit');
SSViewer::set_theme('another');
Something else"""

import re
replaced = re.sub("SSViewer::set_theme\('[a-z]+'\)", "SSViewer::set_theme('whatever')", my_string)
print replaced

produces:

Some file with some other junk
SSViewer::set_theme('whatever');
SSViewer::set_theme('whatever');
Something else

if you want to do it to a file:

my_string = open('myfile', 'r').read()
