Removing items in a list - cap510 - Nov-01-2020 I have tried removing multiple items from a list, but the loop ends without the ability to continue. I am to create a list of names and then use a loop to remove more than one name. names = [] while True: first = input("Enter first name or q to quit: ") if first.lower() == "q": break names.append(first) print() namesL = names[:] while True: x_name = input("Enter a name to remove or q to quit: ") namesL.remove(x_name) names.append(namesL) if first.lower() == "q": break else: continue print(namesL)The second while loop ends without prompting for more entries. I have tried to append list, but still does not work.I am trying to ask user to enter names and remove them from list until they enter q to quit. [/python] RE: Removing items in a list - GOTO10 - Nov-01-2020 On line 13 you are checking the value of first.lower() . Look at your logic again and make sure that is the variable you want to check at that point. Also, consider what happens on line 11 if a user entered "q" on line 10.
RE: Removing items in a list - Larz60+ - Nov-01-2020 you don't need lines 15 and 16 look at these two lines, what's wrong here?: namesL.remove(x_name) names.append(namesL)first you are deleting from namesL. OK, that entry is gone. But now you are trying to add it back to the original list 'name'. Also first was set to 'q' in forst loop, so is still equal to 'q' when you get to line 13, so loop terminates.
