python - 将工资从一维数组转换为二维数组

Question

我创建了一个工资系统，用于计算工资总额、税金和 Netty 。我可以让它从员工列表中创建一个一维数组。输出每位工作人员的总税额和 Netty 。我想要回答的主要问题(第一个问题)是。

1. 主要是我想将一维数组转换为二维数组。 (我不想使用 NUMPY)

如果可以的话您能解释一下下面的两点

当我连接小时和工作时间时，当我使用逗号时会出现错误，但当我使用 + 时不会出现错误，这是为什么

如何对输出进行编码，以便它显示货币的值(value)，例如 $

这是我的输出 atm

output -: ['Kyle', '3,025.00', '605.00', '2,420.00', 'John', '3,025.00', '605.00', '2,420.00', 'Peter', '3,025.00', '605.00', '2,420.00', 'Harry', '3,025.00', '605.00', '2,420.00']

谢谢

我尝试使用嵌套 for 循环来转换 1darray，但我不是高级编码员，无法实现此目的

#wages system to work out gross tax and net
#me
# #16/9/2019

#this is 20 percent of the gross for tax purposes
taxrate=0.2
#blank list

mylistwage=[]

def calc(i):
#input how much paid per hour joined with first iteration of for loop ie 
#persons name
    pph = float(input("how much does "+ i+ " get paid an hour"))
#as above but different question
    hw = float(input("how many hours did "+ i+" work this week"))
#calculates the weekly gross wage
    gross=hw*pph
#calculates tax needed to be paid
    tax=gross*taxrate
#calculates how much your take home pay is
    net=gross-tax
#adds the gross tax and wage to a one dimentionsal list
    mylistwage.append(i)
#formats appended list so that it is to 2 decimal float appends 3 values
    mylistwage.append(format(gross,",.2f"))
    mylistwage.append(format(tax,",.2f"))
    mylistwage.append(format(net,",.2f"))



mylist=["Kyle","John","Peter","Harry"]
for i in (mylist):
    calc(i)
print(mylistwage)

Answer 1

一种方法是在 calc 方法中创建一个本地列表，然后添加必须添加到该列表中的任何信息并返回该列表。

现在，在 for 循环中迭代 mylist 时，每次只需将其附加到 mainlistwage 变量中。我建议对代码进行以下更改:添加 CAP 注释作为说明。

#wages system to work out gross tax and net
#me
# #16/9/2019

#this is 20 percent of the gross for tax purposes
taxrate=0.2
#blank list

mainlistwage=[] #CHANGING VARIABLE NAME HERE

def calc(i):
    mylistwage = []  #CREATING LOCAL VARIABLE
#input how much paid per hour joined with first iteration of for loop ie 
#persons name
    pph = float(input("how much does "+ i+ " get paid an hour"))
#as above but different question
    hw = float(input("how many hours did "+ i+" work this week"))
#calculates the weekly gross wage
    gross=hw*pph
#calculates tax needed to be paid
    tax=gross*taxrate
#calculates how much your take home pay is
    net=gross-tax
#adds the gross tax and wage to a one dimentionsal list
    mylistwage.append(i)
#formats appended list so that it is to 2 decimal float appends 3 values
    mylistwage.append(format(gross,",.2f"))
    mylistwage.append(format(tax,",.2f"))
    mylistwage.append(format(net,",.2f"))
    return mylistwage    # ADDING RETURN STATEMENT


mylist=["Kyle","John","Peter","Harry"]
for i in (mylist):
    mainlistwage.append(calc(i))  # APPENDING EACH RETURN LIST TO MAINLIST VARIABLE
print(mainlistwage)
