creating a list during program execution.

[hobbyprogrammer]

Is there any way of writing code, that will allow python to create
a list during the program execution. As of now I understand, that you
have to define a list in the hard coding process. But I would like to be
able to create a list as the program is executing, the commands.

Is this possible?
Thank you for anyone taking the time to answer this question.

Totally. Very common operation:

# file to list
data = open('data_file.txt').readlines()

# string to list
text = input('Type in a sentence: ')
words = text.split()

# build from numbers
fib = [1, 1]
for index in range(100):
    fib.append(fib[-1] + fib[-2])
