Here's the algorithm. If you know enough Python you will be able to code 
it. So put together a program, give it a try and come back with questions.

read the file into a string variable (assuming the file is not humungus)
find the location of "something" in the string
assemble a new string consisting of:
   the original string up to the location (index) of "something"
   "what"
   the rest of the original string
write the new string to the file
