Python replace function [replace once]

Question

I need help with a program I\'m making in Python.

Assume I wanted to replace every instance of the word \"steak\" to \"ghost\" (just go wit

Answer 1

Rename one of the words to a temp value that doesn't occur in the text. Note this wouldn't be the most efficient way for a very large text. For that a re.sub might be more appropriate.

 s="The scary ghost ordered an expensive steak"
 print s
 s=s.replace("steak","temp")
 s=s.replace("ghost","steak")
 S=s.replace("temp","steak")
 print s
