Python：比較CSV文件並保存與第一行的區別（列名）

Question

我有兩個CSV文件，如下所示：

文件1 ： June_01_2018.csv

文件2 ： June_02_2018.csv

注意 ：我想找到這兩個文件之間的區別，並將其與列標題一起存儲到第三個文件中。

我的嘗試 ：

with open('June_01_2018.csv', 'r') as f1:
    file1 = f1.readlines()

with open('June_02_2018.csv', 'r') as f2:
    file2 = f2.readlines()

with open('June_Updates.csv', 'w') as outFile:
    for line in file2:
        if line not in file1:
            outFile.write(line)

但是無法將列標題存儲到第三個文件中。

Answer 1

嘗試這個：

    with open('June_01_2018.csv', 'r') as f1:
        file1 = f1.readlines()

    with open('June_02_2018.csv', 'r') as f2:
        file2 = f2.readlines()

    with open('June_Updates.csv', 'w') as outFile:
        outFile.write(file1[0])
        for line in file2:
            if line not in file1:
                outFile.write(line)
