Tuples in Python
Introduction
Python tuples are a data structure that stores
an ordered sequence of values. Tuples are inflexible. This means you cannot
change the values in a tuple. They let you store an ordered sequence of
particulars. For illustration, you may use a tuple to store a list of hand
names.
Data stored in a tuple are penetrated using
their indicator, for the tuple indicator will always start from Zero. Each
element has a specific place in the tuple and all of those data are penetrated
with the help of the indicator.
Defining and Using Tuples
Tuples are identical to lists in all felicitations,
except for the following parcels
Tuples are defined by enclosing the rudiments in hiatuses ( ()) rather
of square classes ( ()).
Tuples are inflexible.
Why use a tuple rather than a
list?
Program prosecution is briskly when
manipulating a tuple than it's for the original list. (This is presumably not
going to be conspicuous when the list or tuple is small.)
Occasionally you don’t want data to be
modified. However, using a tuple rather than list guards against accidental
revision, If the values in the collection are meant to remain constant for the
life of the program.
There's another Python data type that you'll
encounter shortly called a wordbook, which requires as one of its factors a
value that's of an inflexible type. A tuple can be used for this purpose,
whereas a list can’t be.
Creating Tuples
Tuple stored its data with comma-separated and is enclosed in a
bracket (). Tuples can contain different types of items of any number.
Syntax:
Tuple = (item1, item2, item3)
Example
tuple1 = (10, 20, 30, 40, 50, 60)
Tuples
and lists are both quite similar and
used in similar situations.
Below listed are some of the advantages of
tuples over a list implementation.
Advantages
· We generally use tuples for miscellaneous (different) data types
and lists for homogeneous (analogous) data types.
· Since tuples are inflexible, repeating through a tuple is faster
than with a list. So there's a slight performance boost.
· Tuples that contain inflexible rudiments can be used as a key for
a wordbook. With lists, this isn't possible.
· Still, enforcing it as a tuple will guarantee that it remains
written-defended. If you have data that does not change.
