【问题描述】：

我有 4 个arrays 想要打印到如下所示的表格中：

Item Code, Item, Price, Item Stock
001, Pencil, 10, 738

等等从这4个arrays:

item_code = ["Item Code", "001", "002", "003", "004", "005", "006", "007", "008", "009", "010"]

item = ["Item", "Pencil", "Pen", "Eraser", "Paper", "Notebook", "Highlighters", "Card", "Stapler", "Paperclip", "Marker"]

item_price = ["Price", "10", "5", "2", "15", "20", "23", "26", "13", "17", "21"]

item_stock = stock() # This is calculated in another subheading

我该怎么做？

【解决方案1】：

您可以为此使用zip：

z = zip(item_code, item, item_price, item_stock)
for code, i, price, stock in z:
    print(code, i, price, stock)

【讨论】：

甚至更好：for i in z: print(*i)

【解决方案2】：

一种选择是使用 Pandas：

import pandas as pd
df = pd.DataFrame([item_code[1:], item[1:], item_price[1:]], index=[item_code[0], item[0], item_price[0]]).T
print(df)


  Item Code          Item Price
0       001        Pencil    10
1       002           Pen     5
2       003        Eraser     2
3       004         Paper    15
4       005      Notebook    20
5       006  Highlighters    23
6       007          Card    26
7       008       Stapler    13
8       009     Paperclip    17
9       010        Marker    21

你不应该使用他没有要求的库来给出答案，没有它很容易做到这一点

【解决方案3】：

使用简单的 for 循环：


for i in range(len(item_code)):
  print(item_code[i], item[i], item_price[i], item_stock[i])

【讨论】：

【解决方案4】：

使用简单的 for 循环，你可以对 item_stock 做同样的事情

item_code = ["Item Code", "001", "002", "003", "004", "005", "006", "007", "008", "009", "010"]

item = ["Item", "Pencil", "Pen", "Eraser", "Paper", "Notebook", "Highlighters", "Card", "Stapler", "Paperclip", "Marker"]

item_price = ["Price", "10", "5", "2", "15", "20", "23", "26", "13", "17", "21"]

for i in range (len(item)):
    
    print(item_code[i],item[i],item_price[i])

输出：

Item Code Item Price
001 Pencil 10
002 Pen 5
003 Eraser 2
004 Paper 15
005 Notebook 20
006 Highlighters 23
007 Card 26
008 Stapler 13
009 Paperclip 17
010 Marker 21

【解决方案5】：

使用 f 字符串更优雅的打印方式

item_code = ["Item Code", "001", "002", "003", "004", "005", "006", "007", "008", "009", "010"]

item = ["Item", "Pencil", "Pen", "Eraser", "Paper", "Notebook", "Highlighters", "Card", "Stapler", "Paperclip", "Marker"]

item_price = ["Price", "10", "5", "2", "15", "20", "23", "26", "13", "17", "21"]

item_stock = ["Item Stock", "10", "5", "2", "15", "20", "23", "26", "13", "17", "21"]

for item_code, item, item_price, item_stock in zip(item_code, item, item_price, item_stock):
    print(f'{item_code},{item},{item_price},{item_stock}')

Output:
Item Code,Item,Price,Item Stock
001,Pencil,10,10
002,Pen,5,5
003,Eraser,2,2
004,Paper,15,15
005,Notebook,20,20
006,Highlighters,23,23
007,Card,26,26
008,Stapler,13,13
009,Paperclip,17,17
010,Marker,21,21
