Python Lambda Functions Explained for Network Engineers

In this video, we will learn about lambda functions in Python. Below is the code I used in the video: A lambda function in Python is an anonymous, one-line function using the lambda keyword. It can take multiple parameters but must contain only one expression. Lambda functions are commonly used with functions like map(), filter(), and sorted(). Syntax: lambda parameters: expression Example 1: Simple Addition using Lambda add = lambda x, y: x + y print(add(5, 3)) Regular function for addition def add(x, y): return x + y print(add(5, 3)) Example 2: Extracting the Last Octet of an IP Address This lambda function splits the IP address by '.' and returns the last octet. get_last_octet = lambda ip: ip.split(".")[-1] print(get_last_octet("192.168.1.100")) print(get_last_octet("10.0.0.5")) Example 3: Checking If an IP is in a Private Range This lambda function returns True if the IP belongs to a private range. is_private_ip = lambda ip: ip.startswith(("192.168.", "10.", "172.16.")) print(is_private_ip("192.168.1.1")) print(is_private_ip("8.8.8.8")) Example 4: Checking If a Port is Open This lambda function returns 'Open' if the port number is in the allowed list, otherwise 'Closed'. is_port_open = lambda port: "Open" if port in [22, 80, 443] else "Closed" print(is_port_open(22)) print(is_port_open(8080)) #python #networkautomation #coding
