Python 我试图在用户只单击enter时停止循环？

当用户输入一个数字时，我试图停止这个循环，调用

input（）

和

int（）

，这两个步骤是分开的

while True:
    # call input() by itself, without calling int()
    answer = input('Type a number, [to stop type 0 or less]')

    # if the user pressed enter without typing an answer, break
    if not answer:
        break

    # otherwise convert answer to an integer
    number = int(answer)

    # remaining code is unchanged

告诉您一个空字符串（当只按enter键时返回）的计算结果为False，这可能是有用的。不管怎样，我还是投了赞成票

while True:
    # call input() by itself, without calling int()
    answer = input('Type a number, [to stop type 0 or less]')

    # if the user pressed enter without typing an answer, break
    if not answer:
        break

    # otherwise convert answer to an integer
    number = int(answer)

    # remaining code is unchanged
