如何在Python中鏈接

Question

我剛開始學習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? ") 

當寄存器放入輸入時，我試圖鏈接到地標標記20區域。我怎麼能做到這一點？謝謝，我只是一個初學者。 :)

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? ") 

更改它這樣，你應該告訴到Python這是一個字符串，因爲存儲變量作爲字符串input。你也可以這樣寫 - 比你的代碼清晰;

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聲明，你必須將register字改爲"register"因爲變量command將是一個字符串的方法：因此if語句尋找==後的字符串。 希望這有助於
