Character Count
It's a practice project for python beginners.
👉 No.1 Write a short program characterCount.py that counts the number of occurrences of each letter in a given string message = 'It was a bright cold day in April, and the clocks were striking thirteen.'.
HINT: The program should loop over each character in the message variable’s string, counting how often each character appears.
The setdefault() method call ensures that the key is in the count dictionary (with a default value of 0), so the program doesn’t throw a KeyError error.
When you run your program, the output should look like this:
{' ': 13, ',': 1, '.': 1, 'A': 1, 'I': 1, 'a': 4, 'c': 3, 'b': 1, 'e': 5, 'd': 3, 'g': 2, 'i': 6, 'h': 3,
'k': 2, 'l': 3, 'o': 2, 'n': 4, 'p': 1, 's': 3, 'r': 5, 't': 6, 'w': 2, 'y': 1}
From your output, you should be able to see that the lowercase letter c appears 3 times, the space character appears 13 times, and the uppercase letter A appears 1 time. This program should work with no matter what string is inside the message variable, even if the string is millions of characters long!
