Question

HINT:

USE def count_letters function:

DO NOT use Length Function!!!!!!!!!!!!!!!!!!!!!!!!

use string format to display percentage. "{:.1f}".format

DO NOT USE ROUND

PYTHON:

1. Develop a program that asks the user to enter a text. The program should analyze the text and print out unique letters, in alphabetical order, with the percentage information of each letter. Case should be ignored. Write a function to analyze the text string. No global variables are used in the function. Function parameters must be used.
   
   Hint: You can convert all letters into lowercase before processing.
   
   A sample run of the program might look this. Show one decimal place percentage:

Please enter a sentence: This is String g 8.3% h 8.3% i 25.0% n 8.3% r 8.3% s 25.0% t 16.7%

HINT:

USE def count_letters function:

Screenshot of the code:

CODE:

def count_letters(s):

#result dictionary

d={}

#for every character i in string s

for i in s:

#if i is not alphabet, ignore it

if i.isalpha()==False:

continue

#add the character to result if it is not present, increment by 1 if its already present

if i in d:

d[i]+=1

else:

d[i]=1

#reutn the result

return d

#take input

s=input("Please enter a sentence: ")

#convert to lower case

s=s.lower()

#count letters using the above function

d=count_letters(s)

#total count=0

total=0

#get the total number of letters in the senetence

for i in d:

total+=d[i]

#for every letter in keys of count dictionry(sortted order)

for i in sorted(d.keys()):

#print the percentage, using {:.1f} format

print(i+" {:.1f}".format((d[i]/total)*100))
