Python count List function is used to count how many times an item is repeated in a given list, and the syntax of it is
list_name.count(list_item)
This function counts the total number of times the item is 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 = 2Let 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 = 4This time, we used the count function on the Nested list (one inside the another).
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 = 2In this example, we sued both the string and integer lists to count the number of times an item is repeated.
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 = 1Example 2
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))
Example 3
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
