Intermediate Python Tutorial #1 - Optional Parameters

Welcome to a new series! Intermediate Python Tutorials!

Today's Topic: optional parameters, these are an extremely useful tool to use within methods and functions to set a default value for any given parameter.

In this set of videos I will be explaining more advanced programming concepts and showing you intermediate-advanced tools that you can use in python. A lot of these tools will help you to solve problems/code more efficiently and will save you a ton of time!

Future topics:
2. Static and Class Methods
3. Map Function
4. Filter Function
5. Lambda Functions
6. Intro to Collections
7. Collections: named tuple
8. Collections: deque
9. Collections: orderedDict
10. Collections: defualtDict
11. docstrings

In the example where you have multiple default parameters and you only want to access the last parameter(freq for his case), you don't have to assign add as 5, you can explicitly call freq to be equal to 3.

def func(word, add=5, freq=1):
print(word*(add+freq))
func("hello", freq=3)

this leaves add as the default and only affects freq

[melidobello]

Thanks a lot... I'm getting into it...

class person(object):

def __init__(self, name, age, body_Weight, height):
self.name = name
self.age = age
self.body_Weight = body_Weight
self.height = height

def definition(self, age_Stage=True):
print("Your name is %s, you're %s years old. You have a body Weight of %s pounds, and a height of %s ft." %(self.name, self.age, self.body_Weight, self.height))
print("Based, on his age: ")
if age_Stage == True:
print("You are an adult")

if age_Stage == False:
print("You are not an adult")

p1 = person('Jonny', '30', '180', '6')
p1.definition(True)

[amazingmaths]

Didn't understand the last one please make a separate video and describe every line....hoping for ur positive response

[Rayantheproofficial]

Why do we need to learn this when we can just print what we want . Its more simple .
We can just print it agian if we need it multiple times in our program .

[kaaljai]

%s where was this explained? It was not, even in beginner's video

[Sciencedoneright]

didn't you do this in the beginner class?

[deus]

Am SOOO GLAD for THIS You're great!!!!

[jccatilo]

can't seem to make the %s %s to work. gives the error "TypeError: not all arguments converted during string formatting".
But I know the " {} ".format(variable_name) thing and it worked out.

def display(self, showAll):
if showAll:
print("This car is a {} {} from {}, it is {} and has {} kms." .format(self.make, self.model, self.year, self.condition, self.kms))
else:
print("This car is a {} {} from {}." .format(self.make, self.model, self.year))

[Sciencedoneright]

This is so fun! doesn't even give the tutorial hell thing!

[wietskevanderwesthuizen]

Why do you always use self.(argument) is there a spesific reason
