Python repr() Function returns a printable representation of an object in Python. In other words, we can say that the Python repr() function returns a printable representation of the object by converting that object to a string.
Example
In the code, repr(s) returns the string ‘Hello, Geeks.’ enclosed in single quotes. repr(2.0/11.0) calculates the division of 2.0 by 11.0 and returns the result as a string without any formatting or rounding.
Python3
s = 'Hello, Geeks.'print (repr(s))print (repr(2.0/11.0)) |
Output :
'Hello, Geeks.'

Python repr() Function Syntax
Syntax: repr(object)
- object: The object whose printable representation is to be returned.
Return: str, printable representation of the object.
How repr() works in Python?
Here we assign an integer value of 10 to a variable x and the repr() of x is returning the value 10 as a string class.
Python3
x = 10print(type(repr(x))) |
Output :
<class 'str'>
repr() in Python Examples
Passing List to repr() in Python
In this example, we are using repr() on the list.
Python3
print(repr(['a', 'b', 'c'])) |
Output :
['a', 'b', 'c']
Passing string object to repr() method
In this example, we are calling the repr() on the string object in Python.
Python3
strObj = 'neveropen'print(repr(strObj)) |
Output :
'neveropen'
Passing a set object to the repr() method
In this example, we have created a set. The set includes numbers from 1 to 5 and we are calling the repr() on the set.
Python3
num = {1, 2, 3, 4, 5}# printable representation of the setprintable_num = repr(num)print(printable_num) |
Output :
{1, 2, 3, 4, 5}
Implement __repr__() for custom objects
In this example, the Person class has a __repr__() method that returns a string representation of the Person object. The repr(person) call returns the string representation defined by the __repr__() method, which is then printed to the console.
Python3
class Person: def __init__(self, name, age): self.name = name self.age = age def __repr__(self): return f"Person(name='{self.name}', age={self.age})"person = Person("John", 25)print(repr(person)) |
Output :
Person(name='John', age=25)
