In this Python program, we will learn how to count the total number of alphabets, digits, and special characters in a given string. In this program, we will use loops and built-in python functions to count the total number of alphabets, digits, and special characters in a given string.

Here is the Source code of the program to count the total number of alphabets, digits, and special characters in a given string.

To Count Alphabets, Digits and Special Characters in a String using For Loop, isalpha() and isdigit() function

```
# To Count Alphabets, Digits and Special Characters in a String using For Loop,
# isalpha() and isdigit() function
# Take the Input From the User
string = input("Enter the String: ")
alphabets = digits = special = 0
for i in range(len(string)):
if(string[i].isalpha()):
alphabets = alphabets + 1
elif(string[i].isdigit()):
digits = digits + 1
else:
special = special + 1
print("\nTotal Number of Alphabets in this String: ", alphabets)
print("Total Number of Digits in this String: ", digits)
print("Total Number of Special Characters in this String: ", special)
```
