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:
