LAMBDA FUNCTIONS
I’m going to show you a quick easy way to create one line functions in python
These are particularly helpful for computational functions
to create a lambda function type the name of a variable, (we will do f) equals, lambda, a name of another variable (we will do x) colon, then use the second variable to create a function. In this first example we will do x squared
Now to call the function we write the name of it with a value in parenthesis to plug in as x
So 5 squared is 25 and 3.22 squared is 10.368…
In this next example we create a lambda function with an if statement
So our function will be 1 or -1 depending on the value we give it. This has endless applications when coding.
For our last example we will import numpy
This is a three dimensional example. We define the function the same way, only this time when we write the actual function part we treat x as if it is a vector with three values. x[0] is the first entry of the vector
This function will sum the values of our vector, and require that we put a vector of size 3 in
Lambda functions can also be plotted with marplot lib, check the description for a video on how to plot lambda functions
So there you have it, that is how you use lambda functions in python
