Python count List function is used to count how many times an item is repeated in a given list, and its syntax is shown below
list_name.count(list_item)
This Python function counts the total number of times the item repeated in a given list. The below code counts 10 and 20 in an integer list.
a = [10, 20, 30, 10, 40, 10, 50, 20]
print("Total Number of Times 10 has repeated = ", a.count(10))
print("Total Number of Times 20 has repeated = ", a.count(20))
Total Number of Times 10 has repeated = 3
Total Number of Times 20 has repeated = 2Python count List Example
In this example, we declared a string list, and then we used the count function on it.
Fruits = ['Apple', 'Orange', 'Banana', 'Apple', 'Grape', 'Banana', 'Apple']
print("Total Number of Times 'Apple' has repeated = ", Fruits.count('Apple'))
print("Total Number of Times 'Banana' has repeated = ", Fruits.count('Banana'))
Total Number of Times 'Apple' has repeated = 3
Total Number of Times 'Banana' has repeated = 2How to count Mixed List?
Let me use this count function on Mixed List. Please refer to the List and methods articles in Python.
MxList = ['Apple', 10, 'Banana', 10, 'Apple', 'Grape', 10, 30, 10, 50, 'Apple']
print("Total Number of Times 'Apple' has repeated = ", MxList.count('Apple'))
print("Total Number of Times 10 has repeated = ", MxList.count(10))
Total Number of Times 'Apple' has repeated = 3
Total Number of Times 10 has repeated = 4How to count Nested List Items?
This time, we used the count function on the Nested list (one inside the other).
MxList = [[10, 20], [20, 30], [10, 20], [40, 50], [10, 80]]
print("Total Number of Times [10,20] has repeated = ", MxList.count([10,20]))
Total Number of Times [10,20] has repeated = 2How to count string List items?
In this example, we used both the string and integer lists to count the number of times an item will repeat.
Fruits = ['Apple', 'Orange', 'Banana', 'Kiwi', 'Apple', 'Kiwi']
numbers = [9, 4, -5, 0, 9, -1, 4, 9]
print("Original : ", Fruits)
#Count of List items
print('Kiwi = ', Fruits.count('Kiwi'))
print('Apple = ', Fruits.count('Apple'))
print('Banana = ', Fruits.count('Banana'))
print("\nOriginal number : ", numbers)
print('9 is repeated = ', numbers.count(9))
print('4 is repeated = ', numbers.count(4))
print('0 is repeated = ', numbers.count(0))
Original : ['Apple', 'Orange', 'Banana', 'Kiwi', 'Apple', 'Kiwi']
Kiwi = 2
Apple = 2
Banana = 1
Original number : [9, 4, -5, 0, 9, -1, 4, 9]
9 is repeated = 3
4 is repeated = 2
0 is repeated = 1How to count user entered integer list items in Python?
This Python program allows the user to enter the length and For Loop to append those numbers to the intCountList. Then we used this method to count item 10.
intCountList = []
number = int(input("Please enter the Total Number of List Elements: "))
for i in range(1, number + 1):
value = int(input("Please enter the Value of %d Element : " %i))
intCountList.append(value)
item = int(input("Please enter the Item that you want to Count: "))
print("Total Number of Times has repeated = ", intCountList.count(item))
How to count user entered string list items in Python?
This program allows users to enter their own string or words and then count the word.
strCountList = []
number = int(input("Please enter the Total Number of Elements: "))
for i in range(1, number + 1):
value = input("Please enter the Value of %d Element : " %i)
strCountList.append(value)
item = input("Please enter the Item that you want to Count: ")
print("Total Number of Times has repeated = ", strCountList.count(item))
Please enter the Total Number of Elements: 5
Please enter the Value of 1 Element : Kiwi
Please enter the Value of 2 Element : Dragon
Please enter the Value of 3 Element : Banana
Please enter the Value of 4 Element : Kiwi
Please enter the Value of 5 Element : Apple
Please enter the Item that you want to Count: Kiwi
Total Number of Times has repeated = 2
