from logging import log as logger # logger 就是 log 的别名 13、动态导入模块 try : from cStringIO import StringIO except ImportError: from StringIO import StringIO # 先尝试从 cStringIO 导入,如果失败了(比如 cStringIO 没有被安装),再尝试从 StringIO 导入。 try 的作用是捕获错误,并在捕获到制定错...
1try:2fromcStringIOimportStringIO3exceptImportError:4fromStringIOimportStringIO 上述代码先尝试从cStringIO导入,如果失败了(比如cStringIO没有被安装),再尝试从StringIO导入。这样,如果cStringIO模块存在,则我们将获得更快的运行速度,如果cStringIO不存在,则顶多代码运行速度会变慢,但不会影响代码的正常执行。 try 的作...

As expected, all of the functions scale linearly. But usingcPickleandcStringIOis over 40 times faster than thepickleandStringIOmodules! How does PyPy compare? A while back I got interested in PyPy. If you can get all the modules you use or alternatives to them working, it sounds very temp...
Python import cStringIO ImportError: No module named 'cStringIO' 在python2中是支持cStringIo的: from cString import StringIo—在python2中是支持的,但是python3中是不支持的,所以需要使用其他的模块来替代的:io模块 这里就是用来操作内存的,在内存存东西,以及在内存中取东西......
