Python has got in-built method — len() to find the size of the list i.e. the length of the list. Index & length: Lists are a collection of items of similar or different data types. Python list method len() returns the number of elements in the list.

List in Python – python list length

list1 = ['Pakainfo', 'python', 2022];
list2 = [9, 8, 7, 6, 5 ];
list3 = ["p", "a", "k", "a"];

Len() Method

website_list = ["Welcome", "Pakainfo", 9, 8, 7]
print ("Number of items in the list = ", len(website_list))

Naive Method

website_list = [ "Welcome", "Pakainfo", 9,2,7 ]
print ("The list is : " + str(website_list))
counter = 0
for i in website_list:
counter = counter + 1
print ("Length of list using naive method is : " + str(counter))

Output:

The list is : ["Welcome", "Pakainfo", 9,8,7]
Length of list using naive method is : 5

get the number of elements in a list

The len() function can be used with several different types in Python.

>>> len([9, 8, 7])
3

How to get the size of a list?

#An example of len() method

#An example of len() method
 
website_list = ['Welcome', 'pakainfo', 'infinityknow', 'w3diy']

for word in website_list:
 
    print(word, "=", len(word))

3 Easy Ways to Find the Length of a List in Python

The len() method to find the length of a list in Python

website_list = ['pakainfo','infinityknow','w3diy','w3school','jdk']
size = len(website_list)
print(size)

Using Python for loop to get the length

website_list = ['pakainfo','infinityknow','w3diy','w3school','jdk']
size = 0
print("Length of the input string:")
for x in website_list:
    size+=1
print(size)

The length_hint() function to get the length of the list

from operator import length_hint 
website_list = ['pakainfo','infinityknow','w3diy','w3school','jdk']
print("Length of the input string:")
size = length_hint(website_list)
print(size)

How to Get Length of an Array in Python?

from array import array
