python - 将工资从一维数组转换为二维数组

问题描述

我创建了一个工资系统，可以计算工资总额、税收和净额。我可以让它从工作人员列表中创建一个一维数组。为每个工作人员输出总税和净额。我想回答的主要问题（第 1 号）是。

  1. 主要我想将一维数组转换为二维数组。（我不想使用 NUMPY）

如果可能的话，你能解释一下下面的两点吗

  1. 当我连接几个小时时，我工作了多少小时，当我使用逗号时出现错误，但当我使用 + 时却没有，这是为什么

  2. 我如何对输出进行编码，以便它向我显示货币的价值，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

我尝试使用嵌套的 for 循环来转换 1darray 但是我不是高级编码器，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)

解决方案

一种方法可以是在 calc 方法中创建一个本地列表，然后在该列表中添加必须添加的任何信息并返回该列表。

现在在 for 循环中迭代 mylist 时只需将每次附加到 mainlistwage 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"))
#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)
