To do this task first we will create a string that contains integer values What you need is to get just the first item in list, written like so k = list[0].The same for v = list[j + 1:] which should just be v = list[2] for the third element of the list returned from the call to >>> s1.split(':')[0] 'U. Example: Here we will get the first IE student id from the list of tuples. The partition () methods returns a tuple with the first element being what is before the delimiter, the second being the delimiter itself and the third being what is after the delimiter. The method does that to the first case of the delimiter it finds on the String, so you can't use it to split in more than 3 without extra work on the code. st2 = '_d' + stArr[1] To split on the last occurrence instead, see partition string in python and get value of last segment after colon. Return a list of the words in the string, using sep as the delimiter string. If maxsplit is given, at most maxsplit splits are done (thus, the list will have at most maxsplit+1 elements). python hello tutorials write program paayi You use the .split () method for splitting a string into a list.
