The argv list contains command-line arguments passed to the script.

import sys
print("Script name:", sys.argv[0])
print("Arguments:", sys.argv[1:])

2. sys.path – Module Search Path:

The path list contains directories where Python searches for modules.

import sys
print("Module search paths:")
for path in sys.path:
    print(path)

3. sys.version – Python Version Information:

The version string provides information about the Python interpreter.

import sys
print("Python version:", sys.version)

4. sys.platform – Operating System Platform:

The platform string indicates the operating system platform.

import sys
print("Operating system platform:", sys.platform)

5. sys.getsizeof() – Object Size in Memory:

The getsizeof() function returns the size of an object in bytes.

import sys
size = sys.getsizeof("Hello, world!")
print("Size of the string:", size, "bytes")

6. sys.exit() – Graceful Exit:

The exit() function terminates the program with an optional exit code.

import sys
print("Exiting the program")
sys.exit(0)

7. sys.maxsize – Maximum Integer Value:

The maxsize integer represents the maximum size of a list or range.

import sys
print("Maximum list size:", sys.maxsize)

8. sys.modules – Loaded Modules:

The modules dictionary contains information about loaded modules.

import sys
print("Loaded modules:")
for module in sys.modules:
    print(module)

9. sys.exc_info() – Exception Information:

The exc_info() function returns information about the current exception.

import sys
try:
    result = 1 / 0
except:
    exc_type, exc_value, exc_traceback = sys.exc_info()
    print("Exception type:", exc_type)
    print("Exception value:", exc_value)
