Question

In Python, write a function numLetters() that keeps prompting the user for words until they hit return (using while loops). The function should then return the percent of 3-letter words that were entered. So, if a user entered ten words and 4 of the words had 3 letters, then the percent of 3-letter words is 40

Answer 1

def numLetters():
   wordsInput=[]   #list for storing words
   #reading words until enter return
   while(True):
       inpt=input("Enter word :")
       if(inpt!="return"):
           wordsInput.append(inpt)
       else:
           break
  
   wordsDigitCount=[] #for storing every word count
   #counting every word count
   for word in wordsInput:
       dcount=0
       for ch in word:
           if(ch.isspace()!= True):
               dcount=dcount+1
       wordsDigitCount.append(dcount)

   #calculating 3 letter word count and percentage
   threeLetter=0
   for i in range(len(wordsDigitCount)):
       if(wordsDigitCount[i]==3):
           threeLetter=threeLetter+1
   return len(wordsInput),threeLetter*10   #returning count of total words and percentage of 3 letter words
      
#main program
totalWords,percentage=numLetters() #storing function return values
print("out of {} words, 3-letter percentage : {}".format(totalWords,percentage))
