I have to remove last non printable data '' from the string.

Answer 1

Assuming your list is called final_line ,

final_line.remove('') should remove '' from list

Answer 2

You can use

list_name.remove('')

in this case. If you want to delete last element from a list:

 list_name = list_name[:-1] 

or

 list_name.pop()
