Python Program to Count Occurrences of Element in List

This is a Python Program to search the number of times a particular number occurs in a list.

The program takes a number and searches the number of times the particular number occurs in a list.

1. Take in the number of elements for the first list and store it in a variable.
2. Take in the elements of the list one by one.
3. Then take in the number to be searched in the list.
4. Use a for loop to traverse through the elements in the list and increment the count variable.
5. Display the value of the count variable which contains the number of times a particular number occurs in a list.
6. Exit.

Here is source code of the Python Program to search the number of times a particular number occurs in a list. The program output is also shown below.

a=[]
n=int(input("Enter number of elements:"))
for i in range(1,n+1):
    b=int(input("Enter element:"))
    a.append(b)
k=0
num=int(input("Enter the number to be counted:"))
for j in a:
    if(j==num):
        k=k+1
print("Number of times",num,"appears is",k)

1. User must enter the number of elements for the first list and store it in a variable.
2. User must then enter the elements of the list one by one using a for loop and store it in a list.
3. User must also enter the number to be search the list for.
4. A for loop is used to traverse through the elements in the list and an if statement is used to count a particular number.
5. The total count of a particular number in the list is printed.

 
Case 1:
Enter number of elements:4
Enter element:23
Enter element:45
Enter element:23
Enter element:67
Enter the number to be counted:23
Number of times 23 appears is 2
 
Case 2:
Enter number of elements:7
Enter element:12
Enter element:45
Enter element:67
Enter element:45
Enter element:67
Enter element:67
Enter element:67
Enter the number to be counted:67
Number of times 67 appears is 4
