Reading unknown number of lines from console

Question

I have to read unknown number of lines from stdin in python3. Is there a way to do this without any modules? One more question: How to denote end of input for multiple lines in python3?

Answer 1

Try something like this

a_lst = []          # Start with empty list
while True:
    a_str = input('Enter item (empty str to exit): ')
    if not a_str:   # Exit on empty string.
        break
    a_lst.append(a_str)
print(a_lst)
