Replace first occurrence only of a string?

Question

I have something like this:

text = \'This text is very very long.\'
replace_words = [\'very\',\'word\']

for word in replace_words:
    text = text.replace(\         


        

Answer 1

text = text.replace("very", "not very", 1)

The third parameter is the maximum number of occurrences that you want to replace.
From the documentation for Python:

string.replace(s, old, new[, maxreplace])
Return a copy of string s with all occurrences of substring old replaced by new. If the optional argument maxreplace is given, the first maxreplace occurrences are replaced.
