Definition and Usage. The index() method finds the first occurrence of the specified value. The index() method raises an exception if the value is not found. The index() method is almost the same as the find() method, the only difference is that the find() method returns -1 if the value is not found. (See example below)When joining strings Python only has to allocate new memory for the final string, which is much more efficient, but could take longer to compute.
