Python types

We have already seen different python types

 # an integer number
a = 30
 
# a floating point number
b = 10.
 
# a string
text = "Hello world"
 
# a function definition
def print_data(data):
	print(data)
    print(type(data))
    
 
# Let's print the data 
# we just defined
print_data(a)
print_data(b)
print_data(text)

What if we want to define our custom type (object)

	class myObject:
	# a minimal Class
	# without attributes
	pass

	class Person:
	# Class attribute
	# (shared by all instances)
	species = "Homo Sapiens"

	def __init__(self, name, age):
	# Instance attributes
	# (specific to each instance)
	self.name = name
	self.age = age

	class Person:

	species = "Homo Sapiens"

	def __init__(self, name, age):
	# Instance attributes
	# (specific to each instance)
	self.name = name
	self.age = age

	def info(self):
	# method (function) to print
	# info related to our object
	print(f"{self.name} is {self.age} years old")
