PYTHON - TUPLES
A
tuple is a sequence of immutable Python objects. Tuples are sequences, just
like lists.
The
differences between tuples and lists are, the tuples cannot be changed unlike
lists and tuples use parentheses, whereas lists use square brackets.
Creating
a tuple is as simple as putting different comma-separated values. Optionally
you can put these comma-separated values between parentheses also. For example
−
|
tup1
= ('physics', 'chemistry', 1997, 2000);
tup2
= (1, 2, 3, 4, 5 );
tup3
= "a", "b", "c", "d";
|
The
empty tuple is written as two parentheses containing nothing −
|
tup1
= ();
|
To
write a tuple containing a single value you have to include a comma, even
though there is only one value −
|
tup1
= (50,);
|
