Python | Convert a list into a tuple
Given a list, write a Python program to convert the given list into a tuple.
Examples:
Input : [1, 2, 3, 4]
Output : (1, 2, 3, 4)
Input : ['a', 'b', 'c']
Output : ('a', 'b', 'c')
Approach #1 : Using tuple(list_name).
Typecasting to tuple can be done by simply using tuple(list_name).
# Python3 program to convert a # list into a tupledef convert(list): return tuple(list) # Driver functionlist = [1, 2, 3, 4]print(convert(list)) |
Output:
(1, 2, 3, 4)
Approach #2 :
A small variation to the above approach is to use a loop inside tuple() .
# Python3 program to convert a # list into a tupledef convert(list): return tuple(i for i in list) # Driver functionlist = [1, 2, 3, 4]print(convert(list)) |
Output:
(1, 2, 3, 4)
Approach #3 : Using (*list, )
This essentially unpacks the list l inside a tuple literal which is created due to the presence of the single comma (, ). This approach is a bit faster but suffers from readability.
# Python3 program to convert a # list into a tupledef convert(list): return (*list, ) # Driver functionlist = [1, 2, 3, 4]print(convert(list)) |
Output:
(1, 2, 3, 4)
