如何做，而與多個條件的循環

Question

我有蟒蛇while循環

condition1=False 
condition1=False 
val = -1 

while condition1==False and condition2==False and val==-1: 
    val,something1,something2 = getstuff() 

    if something1==10: 
     condition1 = True 

    if something2==20: 
     condition2 = True 

' 
' 

我想打出來，當所有這些條件都爲真循環，上面的代碼不工作

我本來有

while True: 
     if condition1==True and condition2==True and val!=-1: 
     break 

哪些工作正常，這是做到這一點的最佳方式？

感謝

Answer 1

更改and s到or秒。

Answer 2

使用像您最初完成的無限循環。它的清潔，如你所願

while 1: 
    if condition1 and condition2: 
     break 
    ... 
    ... 
    if condition3: break 
    ... 
    ... 

Answer 3

while not condition1 or not condition2 or val == -1: 

但沒有什麼不對您如果同時內部真正使用的原，你可以將很多條件。

Answer 4

我不知道它會讀更好，但你可以做到以下幾點：

while any((not condition1, not condition2, val == -1)): 
    val,something1,something2 = getstuff() 

    if something1==10: 
     condition1 = True 

    if something2==20: 
     condition2 = True 

Answer 5

你有沒有注意到，在您發佈的代碼，condition2永遠不會設置爲False？這樣，你的循環體永遠不會被執行。

此外，請注意，在Python中，not condition優於condition == False;同樣，condition優於condition == True。

Answer 6

condition1 = False 
condition2 = False 
val = -1 
#here is the function getstuff is not defined, i hope you define it before 
#calling it into while loop code 

while condition1 and condition2 is False and val == -1: 
#as you can see above , we can write that in a simplified syntax. 
    val,something1,something2 = getstuff() 

    if something1 == 10: 
     condition1 = True 

    elif something2 == 20: 
# here you don't have to use "if" over and over, if have to then write "elif" instead  
    condition2 = True 
# ihope it can be helpfull
