Class objects vs. variables
Class
- Python is an Object-Oriented Programming Language.
- A Class is used to create User-Defined Data Structures.
- Classes have data members and define
methods identify the behavior and actions that can be performed with its data members - Object is the unique instance of a class.
How to create a class and object
class ClassExample:def __init__(self, collegeName):self.collegeName = collegeNamedef display(self):print("My college name is " + self.collegeName)object = ClassExample("GITAM")object.display()
Variables
- A variable is a container used to store data values.
- There is no need to specify a data type to declare a variable.
- It will consider the corresponding data types according to the value that you are assigning to the variable.
code = 12name = "GITAM"branch = "CSE"location = "Visakhapatnam"print(str(code) + " " + name + " " + branch + " " +location)
Casting
- Casting is used to convert a variable value from one data type to another.
- It is also used to specify the type of the variable.
rollno = str(121710303001)name = "Aditya"cgpa = int(7.87)per = float(9)print("Rollno : " , rollno )print("Name :" , name)print("CGPA :" , cgpa)print("Percentage : ", per)
How to check the datatype of a variable
You can get the data type of a variable using the type() function.
rollno = 121710303001name = "Aditya"cgpa = 7.87print(type(rollno))print(type(name))print(type(cgpa))
