Programming - Procedural vs. Object-Oriented
Procedural Approach
- Procedural programming is where a program is divided into elements called functions
- Procedural programming uses a top-bottom approach
# Example of a function
def add(a, b):
# Add the two numbers
total = a + b
return total
# Call the function
add(1, 2)Object-Oriented Approach
- Object Oriented programming is where a program is divided into elements called objects
- Object Oriented programming follows a bottom-top approach
Objects
- Objects can be termed as an entity that can store data as we store in variables
- Objects are entities that have certain characteristics and they can perform certain actions
Objects in general use
- We have already been using objects
# Using the type() function
x = 42 # Object of class int
print(f'x belongs to {type(x)}')
y = 'Python Community' # Object of class str
print(f'y belongs to {type(y)}')
z = ['a', 'b', 'c'] # Object of class list
print(f'z belongs to {type(z)}')
# We can know about the functions of a class object using the dir() function
print(f'The list class has {len(dir(z))} functions. Below mentioned are a few functions: ')
print(dir(z)[-17:-7])
