Learn to get the class name in Python in 2 ways

2 different ways in Python to get the class name:

In this post, I will show you 2 different ways in Python to get and print the class name of an instance. This is commonly used in printing the class name in logs. You can create a common method for logging and call this method from different files or from different class instances. If you print the class name with other logs, it becomes easy to debug.

Method 1: By using class.name:

We can use the class attribute of python. This attribute has one variable called name which is the name of the class.

class attribute can be accessed in an object of a class or in an instance of a class. Let’s take an example:

class Student:
    def sayhello():
        print('Hello from Student')

class Teacher:
    def sayhello():
        print('Hello from Teacher')

s = Student()
t = Teacher()

print(f'Class name of s is: {s.__class__.__name__}')
print(f'Class name of t is: {t.__class__.__name__}')

Here,

We created two classes Student and Teacher.
s is an object of the Student class and t is an object of the Teacher class.
The last two print statements are printing the class names of these two objects.

If you run this program, it will print the below result:

Class name of s is: Student
Class name of t is: Teacher

If you call it on different objects of the same class, it will print the same result.

class Student:
    def sayhello():
        print('Hello from Student')

s = Student()
s1 = Student()
s2 = Student()

print(f'Class name of s is: {s.__class__.__name__}')
print(f'Class name of s1 is: {s1.__class__.__name__}')
print(f'Class name of s2 is: {s2.__class__.__name__}')

It will print:

Class name of s is: Student
Class name of s1 is: Student
Class name of s2 is: Student

Method 2: By using type():

type() function returns the class type for a object. It takes one object as the parameter and returns the type of that object.

For example:

class Student:
    def sayhello():
        print('Hello from Student')

s = Student()

print(f'Class type of s is: {type(s)}')

It will print:

Class type of s is: <class '__main__.Student'>

We can use the name attribute of this value to get the class name. Let’s try it:

class Student:
    def sayhello():
        print('Hello from Student')

s = Student()

print(f'Class name of s is: {type(s).__name__}')

It will print:

Class name of s is: Student

Let’s try with multiple objects:

class Student:
    def sayhello():
        print('Hello from Student')

s = Student()
s1 = Student()
s2 = Student()

print(f'Class name of s is: {type(s).__name__}')
print(f'Class name of s1 is: {type(s1).__name__}')
print(f'Class name of s2 is: {type(s2).__name__}')

It will print the same output.
