python 查看自身安装版本，位数和安装路径，以及获取操作系统详细信息的module介绍
一、想要查看ubuntu中安装的Python路径
方法一：whereis python
方法二：which python
[work@hai-zt-model_save]$ whereis python
python: /usr/bin/python2.7 /usr/bin/python /usr/bin/python2.7-config /usr/lib/python2.7 /usr/lib64/python2.7 /etc/python /usr/include/python2.7 /usr/share/man/man1/python.1.gz
[work@hai-zt-model_save]$ which python
/usr/bin/python
二、需要获取当前安装的python是32位还是64位，由于初学，上网找了一些资料也不奏效，后来咨询前辈才知道的，如下
[work@hai-zt-model_save]$ python
Python 2.7.5 (default, Nov 6 2016, 00:28:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import platform
>>> platform.architecture()
('64bit', 'ELF')
>>>
三、操作系统详细信息
另外，python中，platform模块给我们提供了很多方法去获取操作系统的信息如：
import platform
platform.platform() #获取操作系统名称及版本号，'Windows-7-6.1.7601-SP1'
platform.version() #获取操作系统版本号，'6.1.7601'
platform.architecture() #获取操作系统的位数，('32bit', 'WindowsPE')
platform.machine() #计算机类型，'x86'
platform.node() #计算机的网络名称，'hongjie-PC'
platform.processor() #计算机处理器信息，'x86 Family 16 Model 6 Stepping 3, AuthenticAMD'
platform.uname() #包含上面所有的信息汇总，uname_result(system='Windows', node='hongjie-PC',release='7', version='6.1.7601', machine='x86', processor='x86 Family Model 6 Stepping 3, AuthenticAMD')
还可以获得计算机中python的一些信息：
import platform
platform.python_build()
platform.python_compiler()
platform.python_branch()
platform.python_implementation()
platform.python_revision()
platform.python_version()
platform.python_version_tuple()
四、具体代码示例如下：
# coding:utf-8
import platform
# global var
# 是否显示日志信息
SHOW_LOG = True
def get_platform():
'''获取操作系统名称及版本号'''
return platform.platform()
def get_version():
'''获取操作系统版本号'''
return platform.version()
def get_architecture():
'''获取操作系统的位数'''
return platform.architecture()
def get_machine():

return platform.machine()
def get_node():
'''计算机的网络名称'''
return platform.node()
def get_processor():
'''计算机处理器信息'''
return platform.processor()
def get_system():
'''获取操作系统类型'''
return platform.system()
def get_uname():
'''汇总信息'''
return platform.uname()
def get_python_build():
''' the Python build number and date as strings'''
return platform.python_build()
def get_python_compiler():
'''Returns a string identifying the compiler used for compiling Python'''
return platform.python_compiler()
def get_python_branch():
'''Returns a string identifying the Python implementation SCM branch'''
return platform.python_branch()
def get_python_implementation():
'''Returns a string identifying the Python implementation. Possible return values are: ‘CPython’, ‘IronPython’, ‘Jython’, ‘PyPy’.'''
return platform.python_implementation()
def get_python_version():
'''Returns the Python version as string 'major.minor.patchlevel'
'''
return platform.python_version()
def get_python_revision():
'''Returns a string identifying the Python implementation SCM revision.'''
return platform.python_revision()
def get_python_version_tuple():
'''Returns the Python version as tuple (major, minor, patchlevel) of strings'''
return platform.python_version_tuple()
def show_python_all_info():
'''打印python的全部信息'''
print('The Python build number and date as strings : [{}]'.format(get_python_build()))
print('Returns a string identifying the compiler used for compiling Python : [{}]'.format(get_python_compiler()))
print('Returns a string identifying the Python implementation SCM branch : [{}]'.format(get_python_branch()))
print('Returns a string identifying the Python implementation : [{}]'.format(get_python_implementation()))
print('The version of Python ： [{}]'.format(get_python_version()))
print('Python implementation SCM revision : [{}]'.format(get_python_revision()))
print('Python version as tuple : [{}]'.format(get_python_version_tuple()))
def show_python_info():
'''只打印python的信息，没有解释部分'''
print(get_python_build())
print(get_python_compiler())
print(get_python_branch())
print(get_python_implementation())
print(get_python_version())
print(get_python_revision())
print(get_python_version_tuple())
def show_os_all_info():
'''打印os的全部信息'''
print('获取操作系统名称及版本号 : [{}]'.format(get_platform()))
print('获取操作系统版本号 : [{}]'.format(get_version()))
print('获取操作系统的位数 : [{}]'.format(get_architecture()))
print('计算机类型 : [{}]'.format(get_machine()))
print('计算机的网络名称 : [{}]'.format(get_node()))
print('计算机处理器信息 : [{}]'.format(get_processor()))
print('获取操作系统类型 : [{}]'.format(get_system()))
print('汇总信息 : [{}]'.format(get_uname()))
def show_os_info():
'''只打印os的信息，没有解释部分'''
print(get_platform())
print(get_version())
print(get_architecture())
print(get_machine())
print(get_node())
print(get_processor())
print(get_system())
print(get_uname())
def test():
print('操作系统信息:')
if SHOW_LOG:
show_os_all_info()
else:
show_os_info()
print('#' * 50)
print('计算机中的python信息：')
if SHOW_LOG:
show_python_all_info()
else:
show_python_info()
def init():
global SHOW_LOG
SHOW_LOG = True
def main():
init()
test()
if __name__ == '__main__':
main()
结果如下：
localhost:Attempt_new a6$ python get_system_info.py
