Running while loop from user input and print list after that

Question

I'm learning Python and usage of the stackoverflow so that's why this question might be trivial for you.

So; Code goal is to ask user names until user press enter. After that code should count how many names were given and then print list of the names.

Example

Enter a name:Jack
Enter a name:Dack
Enter a name:Nack
Enter a name:
Name count 3
Jack, Dack, Nack

I have created While true loop for name counting, but now I just can figure out how to simply print those names like in the above.

My code is:

count_names = 0

while True:
    given_names = input("Enter a name: ")
    
    if given_names == "":
            print(f"Name count {count_names}")
            break

    count_names += 1

Result for that is:

Enter a name:Jack
Enter a name:Dack
Enter a name:Nack
Enter a name:
Name count 3

I can feel that the answer is right there but I just can't put my finger on it =/

Thanks again for the help.

you need to store the names in a list and then print that list — Ani, Sep 29 '21 at 16:52
what is the problem? You just don't get the list of names. right? — Yasaman Shokri, Sep 29 '21 at 16:53

You can do it like this:

count_names = 0
names = []

while True:
    given_names = input("Enter a name: ")
    names.append(given_names)

    
    if given_names == "":
            print(f"Name count {count_names}")
            names.remove('')
            
            break

    count_names += 1

for name in names:
    print(name, end=', ')

Here is another way to print the result

count_names = 0
given_names, result = "abc", ""
while given_names != "":
    given_names = input("Enter a name: ")
    result += f"{given_names}, "
    count_names += 1 
    
print(f"Name count {count_names}")
print(result.rstrip(", "))

This gives the answer in right format. Only changes what needed to do was set count_names = -1 so enter is not calculated and removed \n from the first print so there's no empty line between. Thanks Mate! – JmP Sep 29 '21 at 17:55

Using lists is the best idea in terms of simplicity. I also always use join() method to separate list elements by comma.

nameList = []

count = 0

while True:
    name = input('Enter a name: ')
    if name:
        nameList.append(name)
        count += 1
    else:
        print(f'Name count: {count}')
        print(', '.join(nameList))
        break

Try the below code, it will return as you want

    names = '' 
    count_names = 0 
while True:
    given_names = input("Enter a name: ")
    if given_names == "":
        print(f"Name count {count_names}")
        print(names[:-1])
        break
    names += given_names + ','
    count_names += 1
