# uname function -  returns an object containing information about the operating system
# Unfortunately, the uname function only works on some Unix systems. If you use Windows,
# you can use the uname function in the "platform" module, which returns a similar result.

""""
    systemname — stores the name of the operating system;
    nodename — stores the machine name on the network;
    release — stores the operating system release;
    version — stores the operating system version;
    machine — stores the hardware identifier, e.g., x86_64.
    
    posix — you'll get this name if you use Unix;
    nt — you'll get this name if you use Windows;
    java — you'll get this name if your code is written in Jython.

''' SYSTEM function '''
# All functions presented in this part of the course can be replaced by a function called "system", which executes a

# In Windows, it returns the value returned by the shell after running the command given, while in Unix,
#   it returns the exit status of the process.
# The above example will work in both Windows and Unix. In our case, we receive exit status 0, which indicates success
