Python convert string to tuple & list

Let's check the use of python 'tuple' and 'list' in-built functions.

tuple([iterable])

It returns a 'tuple' whose items are the same and in the same order as iterable‘s items. iterable may be a sequence, a container that supports iteration, or an iterator object.

tuple('xyz') returns ('x', 'y', 'z') and tuple([1, 2, 3]) returns (1, 2, 3)

e.g.

$ cat file.txt
Python Prog
Readline
Programming

Now:

>>> for line in open("file.txt"):
...     t = tuple(line)
...     print t
...
('P', 'y', 't', 'h', 'o', 'n', ' ', 'P', 'r', 'o', 'g', '\n')
('R', 'e', 'a', 'd', 'l', 'i', 'n', 'e', '\n')
('P', 'r', 'o', 'g', 'r', 'a', 'm', 'm', 'i', 'n', 'g', '\n')
>>>

list([iterable])

It returns a list whose items are the same and in the same order as iterable‘s items. iterable may be either a sequence, a container that supports iteration, or an iterator object. If iterable is already a list, a copy is made and returned, similar to iterable[:]. For instance, list('xyz') returns ['x', 'y', 'z'] and list( (1, 2, 3) ) returns [1, 2, 3].

>>>
>>> for line in open("file.txt"):
...     l = list(line)
...     print l
...
['P', 'y', 't', 'h', 'o', 'n', ' ', 'P', 'r', 'o', 'g', '\n']
['R', 'e', 'a', 'd', 'l', 'i', 'n', 'e', '\n']
['P', 'r', 'o', 'g', 'r', 'a', 'm', 'm', 'i', 'n', 'g', '\n']
