Tuple in Python
In this article, you will learn all about Python tuples. More specifically, what are tuples, how to make them, when to use them, and the different ways you should be familiar? A tuple in Python is similar to a list. The difference between the two is that we cannot change the elements of a tuple as it is assigned whereas, in a list, the elements can be changed.
What is a tuple give an example?
A tuple is a collection that is ordered and unchangeable. In Python tuples … You can access tuple items by referring to the index number, inside square
Tuple Example:
# Tuple data structure
# tuple can store any data type
# most important tuples are immutable,
# one tuple is created you can’t update
# data inside a tuple
example = ('one','two','three','four')
# no append ,no insert ,no pop , no remove
days = ('monday','tuesday')
# tuple are faster then lists
Method
count , index
len function
slicing
example[0]=1 # tuple do no assine
number = (1,2,3,4,5,6,7.0)
What is nested list with examples?
The list which is inside the list is known as a nested list. Then how can we excess the nested list? Nested lists are obtained by using nested indexing.
Example to Excess Nested List:
my_list = ['p', 'r', 'o', 'b', 'e']
# Output: P
Print (my_list [0])
# Output: o
Print (my_list [2])
# Output: E
Print (my_list [4])
# Error! Only integers can be used for indexing
# my_list [4.0]
# Nested list
n_list = ["Happy", [2,0,1,5]]
# Nested indexing
# Output: A
Print (n_list [0] [1])
# Output: 5
Print (n_list [1] [3])How do you extract an element from a tuple? using for loop
A for loop is used for iterating over a sequence (that is either a list, a tuple, a dictionary, a set, or a string).
This is less like the for a keyword in other programming languages and works more like an iterative method as found in other object-orientated programming languages.
With the for loop, we can execute a set of statements, once for each item in a list, tuple, set, etc.
number = (1,2,3,4,5,6,7.0)
for i in number:
print(i)
