Step 1: What is it ?
- Think of a lambda as a small, one line function.
- It's a quick and simple solution for small tasks, rather than using traditional functions defined with
def.
Step 2: How does the function look?
Lambda x : x+2
This simple (and slightly different looking line) just means: "a function takes x and then returns x+2". That’s it!
Example:
add_two = lambda x : x+2
print(add_two(5)) #output: 7
Explanation: We create a lambda function that takes a number x and adds 2 to it. We pass 5 as value and it returns 7.
Step 3: When to use a lambda function ?
It's very useful for quick, simple tasks like sorting, mapping, or filtering instead of writing a full function.
That’s it! A lambda function is just a short, fast function for simple jobs. And guess what? It’s called an anonymous function because it doesn’t have a name!
As promised, just 3 steps. Happy learning and happy coding!🎉💻
