將用戶輸入與Python中的列表進行比較

Question

如何檢查列表中是否有內容？ 這是我當前的代碼：

for line not in line: open("drivers_details.txt"): 
       if reg not in line: 
        name=input("what is your name?\n") 
        address=input("what is your address\n") 
        print (reg,name,address,"%0.2f"%average_time,"MPH") 

（我試圖用「不」，但它沒有工作）

Answer 1

我想你想：

for line in open("drivers_details.txt"): 
    if reg not in line: 
     etc.
