Python List Operations – Python Tutorial

Python List Operations : In this tutorial, we will learn about different python list operations, some of them are as follows :
- List Concatenation
- List Repetition
- List Contains
- List Not Contains
- List Length
- List Min & Max
List Concatenation
Addition ( + ) operator can be used to join two list together to create a new list.
# create first list object and assign it to variable f
f = [1,2,3,4,5]
# create second list object and assign it to variable s
s = [6,7,8,9,10]
# example of concatenation
concatenate = f + s
print(concatenate)
List Repetition
Multiplication ( * ) operator can be used to join same list multiple times to create a new list.
# create list object and assign it to variable ls
ls = [1,2,3,4]
# example of repetition
repetition = ls * 3
print(repetition)
List Contains
Operator in can be used to check, if a given element is present in the list or not. If a element is present in the list then return True otherwise return False.
# create list object and assign it to variable ls
ls = [1,2,3,4,5]
# example of contains
contains = 1 in ls
print(contains)
List Not Contains
Operator not in can be used to check, if a given element is present in the list or not. If a element is present in the list then return False otherwise return True.
# create list object and assign it to variable ls
ls = [1,2,3,4,5]
# example of not contains
not_contain = 1 not in ls
print(not_contain)
List Length
Python’s len() function can be used to get the length of a list.
Syntax: len(< List Object >)
For example:
# create list object and assign it to variable ls
ls = [1,2,3,4,5]
# call len() method to get length of the list ls
length = len(ls)
# print the value of variable length
print(length)
List Min & Max
Python’s min() and max() function can be used to get minimum and maximum element in the list.
Syntax: min(< List Object >)
max(< List Object >)
For example:
# create list object and assign it to variable ls
ls = [1,2,3,4,5]
# call min() method to get minimum element in the list ls
minimum = min(ls)
# print the value of variable minimum
print(minimum)
# call max() method to get maximum element in the list ls
maximum = max(ls)
# print the value of variable maximum
print(maximum)
