This method returns the last index where the substring str is found, or .1 if no such index exists, optionally restricting the search to string[beg:end].
str.rfind(str, beg=0 end=len(string)) |
Here is the detail of parameters:
str: specifies the string to be searched.
start : starting index, by default its 0
end : ending index, by default its equal to the lenght of the string.
It returns last index if found and -1 otherwise.
#!/usr/bin/python str = "this is really a string example....wow!!!"; str = "is"; print str.rfind(str); print str.rfind(str, 0, 10); print str.rfind(str, 10, 0); print str.find(str); print str.find(str, 0, 10); print str.find(str, 10, 0); |
This will produce following result:
