This article introduces the
__repr__ method in Python.
__repr__ method is a special method used inside a class that represents an object of a class in the form of a string. The in-built
repr() function is utilized to call the
__repr__ method can simply be utilized to produce and define your own string representation of the objects of a class. This method is mainly utilized for debugging in Python.
The syntax for the
__repr__ method is as follows:
We use the keyword
self here as the
__repr__ method is a special method utilized in enriching classes, and the
self keyword represents the instance of the class involved.
The developers tend to generally favor the
__repr__ method as it is unambiguous, while the end-users utilize the
__str__ method because it is easier to read and understand.
This method can simply get called by the in-built
repr() function. Here is an example code that will help make things clearer.
class Employee: def __init__(self, name, age): self.name = name self.age = age def __repr__(self): rep = 'Employee(' + self.name + ',' + str(self.age) + ')' return rep emp = Employee("Archie", 19) print(repr(emp))
The above code provides the following output:
As you can see, the function
repr() takes in a single parameter, the object of the class.
repr() function generally only provides the real-time string representation of an object of the class, but it can be overridden with the help of the
__repr__ method to make it work differently in a way that the user wants.
