Question

PYTHON

You are to write a program that will analyze the frequency of letters in a string. The user will enter a string, your program will output the number of times the letters of the alphabet appear in that string. The user is to enter a string that has upper or lower case letters only, no spaces or other characters. You should convert the string entered to all lowercase letters before you conduct your analysis.

Answer 1

print("This program will find the frequency of letters in a string.")
print("The string you enter must have letters only, no spaces or other characters.")
s = input("Please enter the string: ").lower()

for i in range(26):
    ch = chr(ord('a') + i)
    print(ch + ": " + str(s.count(ch)))
