3、使用ctypes模块 ctypes模块是Python的标准库之一,提供了与C兼容的数据类型,并允许调用函数在动态链接库/shared库中,我们可以使用ctypes.windll.kernel32.SetEnvironmentVariable来设置环境变量。 import ctypes 设置环境变量 ctypes.windll.kernel32.SetEnvironmentVariable('MY_ENV_VAR', 'my_value') 4、使用os.syste...
1import os2print(os.environ.get('VAR1','germey')) 这样即使我们如果设置过 VAR1,他就会用 germey 这个字符串代替,这就完成了默认环境变量的设置。 下面还有几种获取环境变量的方式,总结如下: 1import os2print(os.getenv('VAR1','germey'))
