python --- file difference comparison and consistency check

1. Comparison of document differences

1.1 Code writing

##文件差异性对比
import  difflib
def diff(fn1,fn2):
    """对比两个文件内容的不同并以html格式返回"""
    with open(fn1) as f1:
        content1 = f1.readlines()
    with open(fn2) as f2:
        content2 = f2.readlines()
    df = difflib.HtmlDiff()
    return df.make_file(content1,content2)    ##文件方式对比更好一点
    #return df.make_table(f1,f2)  列表方式对比
# 这句python代码实现了什么功能?
if __name__ == '__main__':
    fn1 = 'doc/file1'
    fn2 = 'doc/file2'
    res = diff(fn1, fn2)
    print(res)

2. Document consistency check

2.1 Code writing
