Learning Python: The Ultimate Guide for Beginners to Coding with Python with Useful Tools

Using User Input to Fill a Dictionary
You can request for input as much as required from a user to pass through a
while loop. The program below is a polling program whereby whenever we
pass  through  the  while  loop,  it  requests  input  from  the  user.  We  will  then
store  the  information  we  gather  from  the  users  in  a  dictionary.  The  idea
behind this is to enable us to link each response we get to a particular user’s
input.
remarks ={}
# let set a flag to indicate that the polling is active
poll_active = True
while poll_active
# request for the name of the user and their remark
fullname = input(“\Enter your full name:”)
remark = input(“What is your country of residence?”)
#store the remark in the dictionary.
remarks[fullname] = remark
#Let us know if someone is still available to take the poll.

---

next = input(“Is there anyone else available to answer a question? (yes/
no)”)
if next == “no”:
poll_active = False
# Our Poll is complete. Therefore, display the results.
Print(“\n**** Poll Results ****”)
for fullname, remark in remarks.item():
print (f “{fullname}, [remark] is my country of residence. “)
In  the  program  above,  we  defined  an  empty  dictionary  (remarks)  while
setting a flag to indicate when the poll is active. The program will continue
to run within the while loop as long as the poll_active is True.
Inside the while loop, the user is requested to enter their full name and their
current  country  of  residence.  The  information  inserted  by  the  user  is  then
stored  in  the  remarks  dictionary.  Additionally,  the  program  then  asks  the
user if they are any person available to take the poll. If the response is yes,
the programs go back to the while loop. However, if it is no, the poll-active
flag becomes false with the loop stops. The final line is the code that will
display the results of the program. let us run the program with the following
input:
Luis Gracious
Herbert Franklin
Lilian Cosmos
Enter your full name: Luis Gracious
What is your country of residence? South Africa
Is there anyone else available to answer a question? (yes/ no) yes

---

Enter your full name: Lilian Cosmos
What is your country of residence? Turkey
Is there anyone else available to answer a question? (yes/ no) yes
Enter your full name: Herbert Franklin
What is your country of residence? Canada
Is there anyone else available to answer a question? (yes/ no) no
**** Poll Results ****
Luis Gracious, South Africa is my country of residence.
Lilian Cosmos, Turkey is my country of residence.
Herbert Franklin, Canada is my country of residence.
