Time to brush up next queued data structure. And its TUPLE.

PYTHON UNLEASH'D 08

Good day geeks!🤗

How to read this blog?

• Be ready with editor opened
• Give one and half min to each section i.e, intro and important
• run programs in between

INTRO

• Indexing ( from 0 OBV )
• Values separated by comma
• Parenthesis () encloses values [not mandatory, but convention]
• Remember parenthesis does not only make it tuple, I can make a tuple without using single bracket also (Inviting reader's views here in comments ⬇⬇) So there are other ways also besides parenthesis

() -> **parenthesis/round brackets**
[] -> **square brackets / big brackets**
{} -> **curly brackets**

• immutable
• heterogenous data

IMPORTANT

Similarities between list and tuple

• Values stored can be indexed
• Values are separated by comma inside
• contain any data type, any number of elements

Unlike lists, tuples are immutable

Creating tuple without parenthesis

Also, the brackets alone do not make an object into a tuple, but it’s not usual to define a integer like this: a = (2)

It’s more common to see: a = 2

It is better to follow what is easier for everyone to understand as long it follows rules.

a = (2)
print(type(a))

a = (1 , 2)
print(type(a))

Other than indexing, we can access tuple items by "unpacking"
See the demo below

Tuple1 = ("Geeks", "For", "Geeks")
# make sure number of var must be equal to total tuple elements
# This line unpack
# values of Tuple1
a, b, c = Tuple1
print("\nValues after unpacking: ")
print(a)
print(b)
print(c)

Concatenation of tuple

Say we have two tuples, tup1 and tup2

tup1 + tup2 is concatenation of both.

Slicing

Slicing rules are same as that for string and list. I request you to see below examples and read slicing on strings once from here

• Negative index can be used in slicing

Example

As tuples are immutable, we can not delete single element from tuple. However we can delete entire tuple at once, with help of del keyword. Lets see how:

# Deleting a Tuple

Tuple1 = (0, 1, 2, 3, 4)
del Tuple1

print(Tuple1)

That's all for tuples.

There is a long list of methods which are unseen and unused for many of us, will see those once start practising.
