有沒有辦法不斷要求用戶輸入一個數字，以便輸入的每個數字將有助於現有字典的價值？

Question

這裏是代碼我的工作：

ans = raw_input('Enter Amount of Players: ').lower() 
cf={} 
if ans == '2': 
    p1 = raw_input('What is Player 1 named:') 
    p2 = raw_input('What is Player 2 named:') 
    cf[p1] = '50' 
    cf[p2] = '50' 
ques = raw_input('Enter Amount Name: ').lower() 
if ques == p1: 
    ques = p1 
elif ques == p2: 
    ques = p2 
elif ques == p3: 
    ques = p3 
elif ques == p4: 
    ques = p4 
elif ques == p5: 
    ques = p5 
elif ques == p6: 
    ques = p6 
elif ques == p7: 
    ques = p7 
elif ques == p8: 
    ques = p8 

inc = raw_input(ques + ' Enter Amount of Increase: ').lower() 
if inc > str(0): 
    def cva(x): 
     y = cf[ques] 
     y = float(y) 
     return x + y 
    num = inc 
    num = float(num) 
    cf[ques]=cva(num) 
    for item in cf: 
     print item, cf[item] 

我如何獲得這樣的：

ques = raw_input('Enter Amount Name: ').lower() 
if ques == p1: 
    ques = p1 
elif ques == p2: 
    ques = p2 
elif ques == p3: 
    ques = p3 
elif ques == p4: 
    ques = p4 
elif ques == p5: 
    ques = p5 
elif ques == p6: 
    ques = p6 
elif ques == p7: 
    ques = p7 
elif ques == p8: 
    ques = p8 

inc = raw_input(ques + ' Enter Amount of Increase: ').lower() 
if inc > str(0): 
    def cva(x): 
     y = cf[ques] 
     y = float(y) 
     return x + y 
    num = inc 
    num = float(num) 
    cf[ques]=cva(num) 
    for item in cf: 
     print item, cf[item] 

要不斷重複無限？我的意思是當用戶輸入一個數字時，該數字將被添加到字典中已經存在的值中。有沒有辦法不斷要求用戶輸入一個數字，以便輸入的每個數字都能爲詞典的價值做出貢獻？

Answer 1

1. 您不需要嵌套if...elif。如果自身設置爲，那麼它是無用的。
2. 使用while True:根據需要啓動死循環。
3. 定義循環外的函數def cva(x)。你不想多次定義它。
4. 更換if inc > str(0)與if int(inc) > 0檢查inc大於0

試試這個：如果你希望它永遠重複的東西

ans = raw_input('Enter Amount of Players: ').lower() 
cf={} 
if ans == '2': 
    p1 = raw_input('What is Player 1 named:') 
    p2 = raw_input('What is Player 2 named:') 
    cf[p1] = '50' 
    cf[p2] = '50' 

def cva(x): 
    y = cf[ques] 
    y = float(y) 
    return x + y 

while True: 
    ques = raw_input('Enter Amount Name: ').lower() 
    inc = raw_input(ques + ' Enter Amount of Increase: ').lower() 
    if int(inc) > 0: 
     cf[ques]=cva(float(inc)) 
     for item in cf: 
      print item, cf[item] 

Answer 2

，你可以嘗試while循環。例如：

p = True 
while p == True: 

你會把這在要重複的代碼，標籤的開始（或者把4個空格）後面的每一行之前。另外，如果你想這樣做對的給定次數，你可以爲循環做：

for x in range(1,1000): 
#Change the 1000 to whatever number you want 

你會把這在你想重複的代碼和標籤前面的代碼了爲好。 如果這不能解決您的問題，請發表評論並說出您需要我解決的問題。
