What Python library is recognized for network scanning capabilities?

The Python library recognized for network scanning capabilities is nmap, specifically accessed through the python-nmap library. This library allows users to interact with the Nmap Network Mapper tool, which is widely used for scanning networks to discover hosts, services, and vulnerabilities. Python-nmap acts as a wrapper around the Nmap command-line tool, providing a convenient way to execute Nmap commands and process their output programmatically within a Python environment.

While other libraries mentioned, such as smtplib and requests, serve specific purposes—smtplib for sending emails via the Simple Mail Transfer Protocol and requests for making HTTP requests—they do not facilitate network scanning. Similarly, the csv library is used for reading and writing CSV files and does not have any functionality related to network activities. Thus, nmap (via the python-nmap library) stands out as the appropriate choice for tasks involving network scanning within Python.
