Alright, so I wanted to mess around with this “eva def” thing I’d been hearing about. I’m not a pro or anything, just a regular dude who likes to tinker.
First, I needed to figure out what the heck “eva def” even was. After some digging around, it seemed like it’s related to defining functions or methods, maybe in a specific programming environment. I’m guessing “eva” is short for “evaluate” or something. No idea, I’m just guessing at this stage.
So, I started by opening up my usual coding playground – just a simple text editor and a terminal. I figured I’d try Python, ’cause it’s pretty easy to play with.
My First Attempt
I typed out a basic function definition:
def my_function(x):
return x 2
Nothing fancy, just a function that doubles whatever number you give it. I saved the file as “eva_*”.
Then, I ran it in the terminal using `python eva_*`. Of course, nothing showed up, because I didn’t actually call the function. Duh.
Calling the Function
I added a line to actually use the function:
def my_function(x):
return x 2
print(my_function(5))
I saved it again and ran it. This time, it printed “10”. Okay, that worked! But it didn’t really tell me anything about “eva def” specifically.
Getting a Bit More “Eva”
I had no clue how to incorporate it into the eva so, I decided to add some printing inside the function to see what was happening:
def my_function(x):
print("Input:", x)
result = x 2
print("Output:", result)
return result
print(my_function(5))
I ran it again. Now it showed:
Input: 5
Output: 10
10
Okay, so it’s showing the input and the output inside the function. Maybe “eva def” is about how the function is evaluated step-by-step? I’m still not sure, to be honest, and I think this is as close as I can get to understanding ‘eva def’.
Wrap Up
Honestly, I’m still a bit confused about what “eva def” is supposed to be. It seems like it’s just about defining functions, and maybe understanding how they’re evaluated. I might need to do some more research later, or maybe someone can explain it to me in the comments. For now, I’ve at least played around with defining and calling a simple function, and that’s good enough for a start!
