python - 不断循环python代码，这样就不会结束

Question

我试图做到这一点，以便即使在我向“输入命令”提供输入后，代码也会在显示最后一个输入是什么后将我带回到提供输入的选项。例如，我希望它在之前完成后不断显示“输入命令”提示。有没有办法在不结束的情况下循环代码？

c1 = "p"
c2 = "d"
c3 = "t"

command = ""
while command != c1:
    print("Enter a command: ")
    print ("(P)profile / (D)data ")
    command = input()
    if command == c1 or command == c2:
        print ("loading...")

        time.sleep(3)

        if command == c1:
            print ("User: Student")
        if command == c2:
            print ("ID: 111111111")

        time.sleep(1)  

    print ("Enter a command: ")
    print ("(P)profile / (D)data ")
    command = input()

Answer 1

将所有内容放入 while True 循环中，并删除要打印并要求输入的最后 3 行(因为您已经在开始时要求输入)这应该有效:

c1 = "p"
c2 = "d"
c3 = "t"

while True:
    print("Enter a command: ")
    print ("(P)profile / (D)data ")

    command = input()
    if command == c1 or command == c2:
        print ("loading...")

        time.sleep(3)

        if command == c1:
            print ("User: Student")
        if command == c2:
            print ("ID: 111111111")

        time.sleep(1)
