Functions Basics 🛠️

Oru velaia thirumba thirumba seiyanum na, adha oru "Function" ulla pottu vechidalam. Adhukapram andha function-a eppa venumo appa "call" panni use pannikkalam. Idhu eppadi na, namba amma seiyura secret "Biriyani Recipe" madhiri! Recipe-a (function) oru thadava ezhudhi vechitta, eppa venumo appa adha paathu biriyani seiyalam.

🔍 Deep Dive: Real-world Analogy (Mixie / Blender 🌪️)

Mixie eppadi work aagum? Adhulla enna pottalum adhu arachu kuduthudum. Mixie-oda ulla irukka motor mechanics ellam namba kitta explain panna theva illa. Namma just button-a pota podhum! Idhe madhiri dhaan, oru periya complex code-a oru peru vechu save panradhu dhaan "Function". Eppa andha code thevayo, andha pera koopta podhum (Function call)!

1. Defining a Function (Recipe Ezhudhudhal)

Oru function create panna def (adhavadhu define) keyword use pannanum:

def say_hello():
    print("Vanakkam da Mapla, Beginner Codes-la irundhu!")
    print("Welcome to Functions!")

Idhoda meaning: say_hello nu oru puthu recipe ezhudhi irukkom. Aana idhu ippo run aagadhu. Recipe book-la ezhudhi vachadhu madhiri just memory-la silent-a irukkum.

2. Calling a Function (Vela vangaradhu!)

Ezhudhi vecha function-a run panna, andha pera vachu () bracket potu kooppidanum:

say_hello() 

Ippo dhaan ulla irukka print run aagum! Neenga 10 thadava say_hello() pota, 10 thadava andha code run aagum. Idhunala lines of code romba kammi aagum!
