如何在Python中链接

Question

我刚开始学习Python。

placemarker = 1 
while True: 
    print ("Welcome") 
    command = input ("Enter command: ") 
    if command == register: 
     placemarker = 20 

if placemarker == 20: 
    registerMe = input ("What is your name? ") 

当寄存器放入输入时，我试图链接到地标标记20区域。我怎么能做到这一点？谢谢，我只是一个初学者。 :)

Answer 1

placemarker = 1 
while True: 
    print ("Welcome") 
    command = input ("Enter command: ") 
    if command == "register": #String variable here 
     placemarker = 20 

if placemarker == 20: 
    registerMe = input ("What is your name? ") 

更改它这样，你应该告诉到Python这是一个字符串，因为存储变量作为字符串input。你也可以这样写 - 比你的代码清晰;

while True: 
    print ("Welcome") 
    command = input ("Enter command: ") 
    if command == "register": #String variable here 
     registerMe = input ("What is your name? ") 
     print (registerMe) #print or do whatever you want on here 
     break 

Answer 2

input()返回String所以在if声明，你必须将register字改为"register"因为变量command将是一个字符串的方法：因此if语句寻找==后的字符串。 希望这有助于
