Right-to-left string replace in Python?

Question

I want to do a string replace in Python, but only do the first instance going from right to left. In an ideal world I\'d have:

myStr = \"mississippi\"
print          


        

Answer 1

It's kind of a dirty hack, but you could reverse the string and replace with also reversed strings.

"mississippi".reverse().replace('iss'.reverse(), 'XXX'.reverse(),1).reverse()
