Choose the correct answerWhich of the following functions is not defined under the sys module?Optionssys.pathsys.argvsys.readlineNone of the above

To determine which function is not defined under the sys module, let’s analyze the options provided:

1. sys.path: This is a list in Python that contains the directories that the interpreter will search for modules in. It is a standard component of the sys module.

2. sys.argv: This is a list in Python that contains the command-line arguments passed to a script. It is also a standard component of the sys module.

3. sys.readline: This is not a function or attribute of the sys module. Instead, it is part of the file module in Python, used to read a line from a file.

4. None of the above: This option implies that all listed functions are indeed part of the sys module, which is not the case here.

Final Answer

The correct answer is sys.readline, as it is not defined under the sys module.
