Hey guys, I am very new to coding so please bare with me. I am busy with a python bootcamp trying to learn as much as quick as I can. I am currently busy with loops, while loops in particular. What I need to make the program do:
ask a user via input command to enter all student names and once he enters "Stop" the loop of asking him/her to enter the next name must stop. I think I have that part sorted. The next part is my struggle:
After the user enters: "Stop" :
The names of the students needs to be printed out, without the "Stop" being printed as that is obviously not a students name.
My attempt at coding the above looks like this:
names = input("Enter student name: ")
while names != "Stop":
names = input("Enter student name: ")
if names == "Stop":
print(names)So the result I am getting is the phrase "Stop" being printed instead of the student names entered prior to "Stop"
I would deeply appreciate some assistance.
Thanks in advance.

You need two variables: one for the name most recently entered, and one for the list of names that have been entered. Call them next_name and names. The input statement goes to next_name. If that's 'stop', you break out of the loop and print names. Otherwise, you append next_name to names.
Thanks for the prompt response ichabod801 I really appreciate it stacks.

Ok,
I gave it a try, but what I am getting is only the first name printed and not more than one name.
The user will obviously enter 1 name, press enter, get requested to enter another name... until he enters "Stop" I only seem to get the first name entered..
I literally started coding past Thursday so please don't get angry with me.
It would be best to explain as if I am a 4 year old. And I apologise if I am proving to be a waste of your precious time.
next_name = input("Enter student name: ")
names = 0
while names != "Stop":
names = input("Enter student name: ")
if names == "Stop":
print(next_name)
Another while loop stumbling block I have is this:
The program needs to ask the user to repeatedly enter a number and stop + exit the loop once the user enters:
"-1"
The program must then calculate the average of the numbers entered excluding the -1.
The first part I think I have correct, but I do not know how to calculate the average of all the inputted numbers prior to " -1 "
Here is what I have so far:
num = int(input("Please enter a number: "))
while num != -1:
num = int(input("Please enter a number: "))
You are keeping your variables separate enough. This is an outline of what your code should look like for both problems:
data = []
while True:
next_datum = input('What is the next whatever? ')
if next_datum == stop_value:
break
data.append(next_datum)
print(data)next_datum is what they just entered. data is a list of everything valid that they entered. stop_value is whatever response stops the loop.
For the one with numbers, you want to look at the int() function to convert strings to integers.

Ok, I see, I will try and recode it following your suggested code outline, thanks again so much for your help I do appreciate it :)
