在打印字典值时，它们不会显示在后面的代码段中

Question

忽略所有这些代码，除了我指出的那些点，我将在这些点上说##Look Here##：

ans = raw_input('Enter Amount of Players: ').lower()

if ans == '2':
    a = raw_input('What is Player 1 named: ')
    b = raw_input('What is Player 2 named: ')
    cf={a:{}, b:{}}
    cf[a] = a
    cf[b] = b
    p1 = raw_input(a + ", what is your city named: ")  
    p2 = raw_input(b + ", what is your city named: ")
    cf={a:{p1:50}, b:{p2:50}}
    ##Look here, print cf ##
    print cf
    for key, cf in cf.items():
        print(key)
        for attribute, value in cf.items():
            print('{} : {}'.format(attribute, value))

answer = raw_input ("Hit 'Enter' to continue")

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

while True:
    one = raw_input("Type 'view' to view civil form, type 'change' to change civil order, or 'add' to add a city: ")
    if one == 'change':
        ques = raw_input('Enter Name of Player That Will Change His/Her Civil Form: ').lower()
        city = raw_input(ques + ' Enter Name Of City That Will Change Civil Form: ').lower()
        inc = raw_input(ques + ' Enter Amount of change for ' + city + ": ").lower()
        ##Look here, print cf##
        print cf
        cf[ques][city]=cva(float(inc))
        for key, cf in cf.items():
            print(key)
            for attribute, value in cf.items():
                print('{} : {}'.format(attribute, value))
    elif one == 'view':
        for key, cf in cf.items():
            print(key)
            for attribute, value in cf.items():
                print('{} : {}'.format(attribute, value))
    elif one == 'add':
        ch1 = raw_input('Enter the Name of Player That Will Add a City: ')
        ch2 = raw_input(ch1 + ', Enter The Name of Your New City: ')
        cf[ch1][ch2] = '50'
    elif one == 'over': break
    elif one == 'game over': break
    elif one == 'quit': break

我告诉你要看的代码的两个部分基本上是打印字典。当我输入名字'Andrew‘和'Matt'，城市'Po’和'Lo‘时，第一张照片是这样的：{'Matt': {'Lo': 50}, 'Andrew': {'Po': 50}}第二张照片是这样的：{'Po': 50}第二张照片像Andrew：{'Lo': 50}为什么球员的名字没有像第一张照片一样出现在第二张照片里。是因为名字被删除了吗？如果是这样，你能告诉我如何解决这个问题吗？

Answer 1

问题出在你的循环上

for key, cf in cf.items():
        for attribute, value in cf.items():
            print('{} : {}'.format(attribute, value))

由于您将其中一个迭代变量命名为与您正在迭代的字典相同的内容，因此您遇到了问题。在此循环之后，cf将包含最后一项的值。

将迭代变量cf重命名为其他名称，如

for key, dict_val in cf.items():
            for attribute, value in dict_val.items():
                print('{} : {}'.format(attribute, value))

一切都会好起来的。
