Python 将工资从一维数组转换为二维数组

我创建了一个工资系统，可以计算工资总额、税金和净额。我可以让它从员工列表中创建一个一维数组。输出每个员工的总税和净税。 我想回答的主要问题是

我主要想把一维数组转换成二维数组。（我不想使用NUMPY）

如果可能，你能解释下面的两点吗

当我将小时数与我工作的多少小时数连接在一起时，当我使用逗号时会出现错误，但当我使用a+时不会出现错误，这是为什么

如何对输出进行编码，使其以货币形式显示值$

这是我的自动取款机

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

我曾尝试使用嵌套for循环来转换1darray，但我不是一名高级编码器，无法实现这一点

#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)

一种方法是在calc方法中创建一个本地列表，然后在该列表中添加任何必须添加的信息并返回该列表

现在在for循环中，在迭代mylist时，只需将每次追加到mainlistsweag变量。 我建议对代码进行以下更改： 添加CAP注释作为解释

#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"))

    return mylistwage    # ADDING RETURN STATEMENT
