实际上，Python提供了with语句来管理资源关闭。比如可以把打开的文件放在with语句中，这样with语句就会帮我们自动关闭文件。with语句的语法格式如下：withcontextexpression[astarget(s)]:with代码块在上面的语法格式中，context_expression用于创建可自动关闭的资源。例如，程序使用with语句来读取文件：importcodecs#使用with语句打开文件，该语句会负责关闭文件withcodecs.

俗话说“画人难画手”，这说明画手是比较难的，为此我们应先了解手的结构。手的结构可分为手掌和手腕两部分，要将手掌看成一个不规则的五边形，作画时，先要将这两部分看作一个整体，画出手的边线，再定出大拇指的位置。要明确每个手指的长度是各不相同的，手指的关节部位要适当弯曲，在特写画面中，要画出手指的两个关节，特别要强调一下拇指和小指的外轮廓线，这样会更有立体感。画手的背面一侧应以硬线勾出，以表现骨骼的硬度，手掌一面要以软线来画，表现柔软的质感。而手指是很灵活的，所以
