4.5 Code Practice Write a loop that inputs words until the user enters STOP. After each input, the program should number each entry and print in this format:

#1: You entered
When STOP is entered, the total number of words entered should be printed in this format:

All done. __ words entered.

Sample Run
Please enter the next word: cat
#1: You entered cat
Please enter the next word: iguana
#2: You entered iguana
Please enter the next word: zebra
#3: You entered zebra
Please enter the next word: dolphin
#4: You entered dolphin
Please enter the next word: STOP
All done. 4 words entered.

The program is an illustration of loops.

Loops are used to perform repetitive operations.

The program in Python, where comments are used to explain each line is as follows:

#This gets input for the first word

word = input("Please enter the next word: ")

#This initializes count to 0

count = 0

#The following iteration is repeated until the user enters "STOP"

while word != "STOP":

   #This prints the word entered

   print("You entered",word)

   #This increments count by 1

   count += 1

   #This gets input for the next words

   word = input("Please enter the next word: ")

#This prints the count of all words

print("All",count,"words entered!")

At the end of the program, the number of valid inputs is printed.

In python 3:

i = 0

while True:

   word = input("Please enter the next word: ")

   if word == "STOP":

       break

   i += 1

   print("#{}: You entered {}".format(i, word))

print("All done. {} word(s) entered.".format(i))

I hope this helps!
