1. Counter of Letters

Write a Python program to create a 'Counter' of the letters in the string "Python Exercise!".

Sample Solution:

Code:

from collections import Counter

text = "Python Exercise!"
letter_counter = Counter(text)

print("Letter Counter:")
for letter, count in letter_counter.items():
    if letter.isalpha():
        print(f"{letter}: {count}")

Output:

Letter Counter:
P: 1
y: 1
t: 1
h: 1
o: 1
n: 1
E: 1
x: 1
e: 2
r: 1
c: 1
i: 1
s: 1

In the exercise above "Counter" class from the "collections" module to count the occurrences of each letter in the given string. It then iterates through the items in the "Counter" and prints the counts of letters that are alphabetic characters.
