如何將多個列表寫入 csv 文件 python3

Question

我有多個列表需要寫入帶有自定義標題的 csv 文件。

一個例子，我有 3 個列表，如下所示。

a = ["Item A", "Item B", "Item C", "Item D"]
b = ["Price A", "Price B", "Price C", "Price D"]
c = ["Stock A", "Stock B", "Stock C", "Stock D"]

我在下面試過

import csv


a = ["Item A", "Item B", "Item C", "Item D"]
b = ["Price A", "Price B", "Price C", "Price D"]
c = ["Stock A", "Stock B", "Stock C", "Stock D"]

c = zip(a, b, c)


with open("test.csv", "w") as f:
    writer = csv.writer(f)
    writer.writerows(c)
    # writer.writerows(c)  

但我希望他們顯示如下

在此處輸入圖像描述

Answer 1

我喜歡使用 pandas 為此使用to_csv ：

import pandas as pd

a = ["Item A", "Item B", "Item C", "Item D"]
b = ["Price A", "Price B", "Price C", "Price D"]
c = ["Stock A", "Stock B", "Stock C", "Stock D"]

data = {'Product': a,
         'List Price': b,
         'In Stock': c}

df = pd.DataFrame.from_dict(data)

df.to_csv('out.csv')

Answer 2

import csv


a = ["Item A", "Item B", "Item C", "Item D"]
b = ["Price A", "Price B", "Price C", "Price D"]
c = ["Stock A", "Stock B", "Stock C", "Stock D"]



with open("test.csv", "w", newline='') as f:
    writer = csv.writer(f)
    for i in range(len(a)):
        content = [a[i], b[i], c[i]]
        writer.writerow(content)
