The program keeps track of how many times an alphabet appears in a given sentence or user-supplied word.

The software was made using Python 3 as follows:

input = user input

"Enter the phrase:"

requests input from the user

User input = char to count[0]

Since it is the first letter in the input program, #subset the letter to count.

user input[1:] word =

The word is #subset

Word.count(char to count) = num counts

Using the count function, determine how many times each letter of the alphabet appears.

If word has char to count:

#verify that the character being counted is present in the word

print(num counts)

#show the frequency of occurrence

else :

print(0)

Print 0 if #ifit doesn't happen.
