We will show you two different ways to calculate total digits in a number. We then interchange the variables (update it) and continue on with the process. Python can handle it with no problem! Pastebin.com is the number one paste tool since 2002. 36. Python Code Counting Rock Samples Problem (TCS CodeVita) | PrepInsta. 35. 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.
