Method Name:
rindex
Method Signature:
rindex(sub[, start[, end]])
Method Overview:
- The rindex() method of str class finds the highest index at which a substring occurs inside a given string object.
- This is similar to the rfind() method of str class. However, the rindex()method raises an exception of type ValueError when the specified substring is not found in the string object.
- rindex()method accepts start index and stop index parameters for the substring search operation.
Example:
|
quoteString = "it means just what I choose it to mean — neither more nor less." substring = "mean" pos = quoteString.rindex(substring)
print("Substring '{}' was found at index:{}".format(substring, pos))
# Now restrict the search for substring between the indices 0 and 10 pos = quoteString.rindex(substring, 0, 10) print("Substring '{}' was found at index:{}".format(substring, pos)) |
Output:
|
Substring 'mean' was found at index:34 Substring 'mean' was found at index:3 |
