[docs] ISSUE I FOUND IN TUPLES

[Vinay Godaba]

Hello I'm Vinay
recently I started learning python and in this process, I noticed there is
a glitch in tuples.
I don't know whether it's a glitch or not but what I noticed is a list
containing single list can identify inner list as a single element of the
list whereas in tuples a tuple containing single tuple is unable to
identify as a single element unless a comma is specified.

# in case of lists
a = [[1,2,3]]
for i in a:
    print(i)   # this outputs [1,2,3]

# in case of tuples
a = ((1,2,3))
for i in a:
    print(i)
# outputs as
1
2
3

# but if we specify comma
a = ((1,2,3),)
for i in a:
    print(i)  # this outputs (1,2,3)
