#Accessing functions
os.function_name(parameters)

Example

#Importing OS module  
import os  
  
#Get the current working directory

Important Points

• The os module requires special privileges to access system-level resources like file systems, user accounts, etc.
• The os module is platform-dependent, meaning that some functions may not work on all operating systems.
• The os module should be used with caution, as system-level operations can have adverse effects if not executed properly.
