    使用textwrap.wrap()

    # 使用textwrap.wrap(s[, width])进行段落划分为list

    使用textwrap.fill

    # 使用textwrap.fill(s[, width])进行换行显示
    print(textwrap.fill(s, width=55)) # 添加"width"属性,表示每一行以单词为单位(包括字符)最大长度不能超过width(55)

    使用textwrap.shorten()

    # 使用textwrap.shorten(s, width[, placeholder])进行缩略显示
    print(textwrap.shorten(s, width=20)) # 表示以单词为单位(包括字符)最长显示width,之后的内容以“[...]”方式缩略显示

    对文本内容进行缩进操作

    使用dedent()

    # dedent()用来取消缩进,比较下面两个输出即可
    print(s)  # 原来定义的s每行前面都有空格
    print(textwrap.dedent(s))  # 使用dedent()之后,有一行是顶格的,其它照着往前缩进
