在循環不以python結束時重復一個函數

Question

嘿伙計們，我正在玩我的小項目，我遇到了關於如何重復一個函數的問題再次調用這個

代碼如下：

 #this function is to check user and pass that was entered by the user using the inputs function

 def chk(u = str(a[0]), p = int(a[1])):
    while u not in sales_man.keys():
    call this function again

Answer 1

如果你想實現一個簡單的登錄，你可以使用經典的無限循環，如：

def check_user(user):
    return user in sales_man.keys()


while True:
    # [...] get username in input

    if check_user(username):
        # [...] ok, check password
    else:
        # [...] wrong user
