How to add user input integers to array?

Question

• Declare an empty array
• Let the user add integers to this array, over and over
• Stop when the user enters -1
• Do not add -1 to the array
• Print the array

So far my code below:

A=[]
while True:
 B = int(input("Input a continuous amount of integers"))
 A = [B]
 print(A)
 if B == -1:
 break
 else:
 continue

• user459872: A.append(B) instead of A = [B]?
• NotAName: A = [B] - This won't work. Here you are creating an array of one element, but your task says that you need to "add integers to array". You need to use append() method.
• NotAName: Also this message makes no sense: input("Input a continuous amount of integers"). It should probably say: Input an integer: or something.
• Matthias: For the future please remember what @BurningAlcohol said in his answer: There is a difference between an array and a list (here you have a list, not an array)

Answer 1

In Python, we call the this [] datatype as list. To append item into a list, you can do A.append(B)

A = []
while True:
 B = int(input("Input a continuous amount of integers"))
 if B == -1:
 break
 else:
 A.append(B) # modify this line
 print(A)

Answer 2

You need to check if user input is -1 before appending it to the array and print it in the if block, append it in the else block.

A=[]
while True:
 B = int(input("Input a continuous amount of integers"))
 
 if B == -1:
 print(A)
 break
 else:
 A.append(B)
