Get Length of List using len() Function in Python | The length of a list is the number of elements in a list, there are many inbuilt features to find python list size. The list is a container that has many elements of similar data types.
Python Program to Find Length of List using len() Function
To find the length of elements in a list we can use the len() function. The len() is a predefined function in python that allows us to find the length of a list. So, we will see the program to get the length of the list in python.
# Python program to find length of list using len function
def length_list(l): #user-defined function
length = len(l) #find length of the list
return length
# take list
list = [1, 2, 3, 4, 5]
# calling function
length = length_list(list)
# print length of the list
print("The length of a list is", length)
Output:-
The length of a list is 5
The above code finds the length of a list in the len() function which takes the list as a parameter.
Get Length of List using len() Function in Python
In the previous program, we will find the length of numbers in a list but in this program, we will find the length of strings in a list using the len() function.
# Python program to find length of list using len function
def length_list(l): #user-defined function
length = len(l) #find length of the list
return length
# take list
list = ['Welcome', 'to', 'Know', 'Program']
# calling function
length = length_list(list)
# print length of the list
print("The length of a list is", length)
Output:-
The length of a list is 4
Python Program to Get Size of List using len() Function
This python program performs the same task but different input values. Here, we will give both numbers and strings in a list.
# Python program to find length of list using len function
def length_list(l): #user-defined function
length = len(l) #find length of the list
return length
# take list
list = [5, 'Hi', 12, 'Know', 'Program']
# calling function
length = length_list(list)
# print length of the list
print("The length of a list is", length)
Output:-
The length of a list is 5
