为我的计算值制作字典

Question

我有一个txt文件，其中包含两个电话号码的列表以及两个号码之间的持续时间，如下所示：

3058 1234 2:28
1650 00777666555 2:03
3928 00423775651 4:54
2222 3333 5:20
3058 00876543210 1:49
3058 1234 1:15
1650 00876543210 2:10
2222 1234 2:32
3928 00172839456 1:38
1111 00969633330 3:01

我已经编写了一个函数来分割数字和时间，并计算它们的价格：

def getSec(time):
    #change minute to second
    min, sec = time.split(':')
    return int(min) * 60 + int(sec)

def calPrice():
    f = open('calls.txt', 'r')
    print(f.read() + '\n')

    with open('calls.txt') as file:
        lines = file.readlines()
        for line in lines:
            anotherLineVar = line.split(' ')
            firstNumb = anotherLineVar[0]
           # print(firstNumb)
            secNumb = anotherLineVar[1]
            #print(secNumb)
            time = anotherLineVar[2]
            #print(time)
            if int(secNumb[0]) == 0:
                second = getSec(time)
                price = second * 1.50

calPrice()

最后一步是，如果任何呼叫包含以00开头的第二个号码，我需要向呼叫号码收取一些费用。我需要在列表中添加收费号码和价格。例如1650 00777666555 2:03和3928 00423775651 4:54的调用将收取184.5和441.0的费用，因此字典将显示为：

{1650:148.5
 3928:441.0}

我试着做一些类似的事情

#outside the if statement
dict = {}
#inside the if statement
dict[secNumb] = price
print(dict)

但结果却是一团糟：

{'00777666555': 184.5}
{'00777666555': 184.5, '00423775651': 441.0}
{'00777666555': 184.5, '00423775651': 441.0, '00876543210': 163.5}
{'00777666555': 184.5, '00423775651': 441.0, '00876543210': 195.0}
{'00777666555': 184.5, '00423775651': 441.0, '00876543210': 195.0, '00172839456': 147.0}
{'00777666555': 184.5, '00423775651': 441.0, '00876543210': 195.0, '00172839456': 147.0, '00969633330': 271.5}

Answer 1

看起来您想用作dictfirstNumb变量的键：

my_dict = {}
my_dict[int(firstNumb)] = price

Answer 2

在dict中，如果希望键是数字，则必须将它们从字符串转换为数字。因为您希望第一个数字作为dict中的键，所以在dict中按它时将其指定为键

试试这个

def getSec(time):
    #change minute to second
    min, sec = time.split(':')
    return int(min) * 60 + int(sec)

def calPrice():
    f = open('calls.txt', 'r')
    print(f.read() + '\n')
    dict = {}
    with open('calls.txt') as file:
        lines = file.readlines()    
        for line in lines:
            anotherLineVar = line.split(' ')
            firstNumb = anotherLineVar[0]
            secNumb = anotherLineVar[1]
            time = anotherLineVar[2]
            if int(secNumb[0]) == 0:
                second = getSec(time)
                price = second * 1.50
                dict[int(firstNumb)] = price
calPrice()
