タプル内の要素の出現をカウントするPythonプログラム

ここでユーザー入力タプルが与えられた場合、私たちのタスクはタプル内の特定の要素の出現をカウントすることです。

例

Input : A = [10, 20, 30, 40, 10, 100, 80, 10]
        X = 10
Output : 3

アルゴリズム

countoccur(A,x)
/* A is an array and x is the element to count the number of occurrences */
Step 1: First we use one counter variable which is count the same element.
Step 2: Then traverse the tuple.
Step 3: Then check x with every element of the tuple.
Step 4: If the element is matched with the x, then counter is incremented by 1.
Step 5: Return counter variable.

サンプルコード

# Program to count occurrences of an element in a tuple 

def countoccur(A, x): 
   c = 0
   for i in A: 
      if (i == x): 
         c = c + 1
   return c 

# Driver Code
A=list()
n1=int(input("Enter the size of the List ::"))
print("Enter the Element of List ::")
for i in range(int(n1)):
   k=int(input(""))
   A.append(k)
n=int(input("Enter an element to count number of occurrences ::"))       
print("Number of Occurrences of ",n,"is",countoccur(A, n)) 

出力

Enter the size of the List ::6
Enter the Element of List ::

12
Enter an element to count number of occurrences :12
Number of Occurrences of 12 is 3
