关于python：比较2个文件并在匹配后将一个值从file1附加到file2的末尾


compare 2 files and append a value from file1 to end of file2 after match

我必须将 FILE1 的 Column1 与 FILE2 的值匹配，如果匹配，请将 FILE1 中的 Column3 附加到 FILE2 中每一行的末尾。

我在下面提供了示例，感谢您提供任何帮助。

您好，请使用以下代码：

file1 = open("input1.txt","r")
file2 = open("input2.txt","r")

file2_array = [data for data in file2]

file = open("output.txt","a")
for row in file1:
    element_to_check = row.split(",")[0]
    for row_to_check in file2_array:
        if element_to_check in row_to_check:
            file.write('%s,%s'%(row_to_check, row.split(",")[2]) + '\
')

此代码从两个输入文件中读取(我假设为文本文件)，然后比较数据，如果满足条件，则将代码附加到该行并将其写入输出文件。
