在两个文件的两行中查找公共元素

def find_common_elements(file1, file2):
    # 读取文件内容并存储到数组或列表中
    with open(file1, 'r') as f1:
        lines1 = f1.readlines()
        lines1 = [line.strip() for line in lines1]
    
    with open(file2, 'r') as f2:
        lines2 = f2.readlines()
        lines2 = [line.strip() for line in lines2]
    
    # 查找公共元素
    common_elements = []
    for line1 in lines1:
        for line2 in lines2:
            if line1 == line2:
                common_elements.append(line1)
    
    return common_elements

# 示例用法
file1 = 'file1.txt'
file2 = 'file2.txt'
result = find_common_elements(file1, file2)
print(result)
