NameError：未定義名稱'q2'

-1

我剛剛在昨天剛剛啓動了python 3，遇到了這個錯誤，我不知道如何解決，請有人幫忙。謝謝！編輯：它不是縮進，對不起，這裏的代碼可能已經結束了錯誤的縮進，當我把它粘貼在這裏，不得不做4間距。NameError：未定義名稱'q2'

q1 = input("Is it currently raining? ") 
if q1 == "Yes": 
    print("You should take the bus.") 
elif q1 == "No": 
    q2=int(input('How far in km do you need to travel? ')) 

if q2 > 10: 
    print("You should take the bus.") 
elif q2 >= 2 and q2 <= 10: 
    print("You should ride your bike.") 
elif q2 == 1: 
    print("You should walk.")

錯誤：

Traceback (most recent call last): 
    File "program.py", line 8, in <module> 
    if q2 > 10: 
NameError: name 'q2' is not defined

請檢查壓痕。 – bereal

你確定你正在運行的Python 3，看起來你是在2.X –

測試你可以通過改變輸入的raw_input來嘗試，因爲輸入在2.x的差異的意義和3 –

你壓痕意味着q2正在檢查即使q1 == "Yes"，嘗試：

q1 = input("Is it currently raining? ") 
if q1.lower() in ("yes", "y"): # more flexible input 
    print("You should take the bus.") 
elif q1 == "No": 
    q2 = int(input('How far in km do you need to travel? ')) 
    if q2 > 10: # inside elif block 
     print("You should take the bus.") 
    elif q2 >= 2: # already know it's 10 or under 
     print("You should ride your bike.") 
    elif q2 == 1: 
     print("You should walk.")
