Method: Using loop + index () + slicing list
This task can be accomplished using the above functions together. In this, we`ll just loop over the pairs and get the desired indexes using index () . Then the list is sliced ​​to create a new list of the desired slice and add it to form a new resulting list.

# Python3 code to demonstrate how it works # Splitting the line list by lines # using loop + index () + slicing list   # initialize the list test_list = [ `gfg` , ` is` , `best` , "for" , `CS` , `and` , ` Maths` ]   # initialize split list split_list = [( ` gfg` , `best` ), ( `CS` , ` Maths` )]   # print original list print ( "The original list is:" + str (test_list))   # print a split list print ( "The split list is:" + str (split_list))   # Splitting the list of lines by lines # using a loop + index () + slicing list for start, end in split_list:   temp1 = test_list.index (start) temp2 = test_list.index (end) + 1 test_list [temp1: temp2] = [test_list [temp1: temp2]]   # print result print ( " The resultant split list is: " + str ( test_list))

Output:

 The original list is: [`gfg`,` is`, `best`,` for`, `CS`,` and`, `Maths`] The split list is: [(` gfg`, `best`), (`CS`,` Maths`)] The resultant split list is: [[`gfg`,` is`, `best`],` for`, [`CS`,` and`, `Maths`]]
