本文实例讲述了python开发中module模块用法。分享给大家供大家参考,具体如下:在python中,我们可以把一些功能模块化,就有一点类似于java中,把一些功能相关或者相同的代码放到一起,这样我们需要用的时候,就可以直接调用了这样做的好处:1,只要写好了一个功能模块,就可以在以后调用,代码的重用就可以体现出来了2,功能写好了以后,不会发生错误。如果一个相同的功能,我们在一个模块中写了一遍,在另外的模块中又写了一遍.......

笔者在 centos6.5 安装 python3.7 碰到此问题,安装好以后,执行 python3.7 命令行,import ssl 出现错误 ImportError: No module named _ssl 。 该错误表现在 pip install 时会报 pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.在网上找了很多资料,经过验证,在编译前修改 python 源码的方式(Modules/Setup.dist)是不奏效的。 升级 openssl 到 1.1.x之后的版本是有...
