Python program counts occurrences of an element in the array; Through this tutorial, you will learn how to count occurrences of each element in an array in python.
Python Count Occurrences of an element in Array
- python program to count occurrences of in array using count.
- python program to count occurrences of in array using for loop.
- python program to count occurrences of in array using function.
Python program to count occurrences of in array using count.
# array list
arr = [1, 2, 2, 2, 2, 3, 4, 7 ,8 ,8]
# count element '2'
count = arr.count(2)
print(count)
After executing the program, the output will be:
4
Python program to count occurrences of in array using for loop
# function to count
def countOccurrences(arr, n, x):
res = 0
for i in range(n):
if x == arr[i]:
res += 1
return res
# array list
arr = [1, 2, 2, 2, 2, 3, 4, 7 ,8 ,8]
n = len(arr)
x = 2
print (countOccurrences(arr, n, x))
After executing the program, the output will be:
4
Python program to count the occurrences in an array using function
#function to count occurence
def Count(x, nums):
count = 0
for num in nums:
if num == x:
count = count + 1
return count
x = 2
#print result
print (Count(x, [1,2,3,4,2,2,2]))
After executing the program, the output will be:
4
