•

• Type open < Python file >.py and press “return” key to open a Python file in the default code editor.
•

• Find the string that you wish to replace.
•

• Type find . -name ‘*.py’ -print0 | xargs -0 sed -I “” ‘s/< old string >/< new string >/g’ (I used double quotes in the example because my strings contained single quotes) and press “return” key to replace a string in all Python files in the directory.
