overview of repr()
The repr() function returns a printable representation of a given object. For many types the return value is a string that would result in the object with the same values if it is evaluated using the eval() function.
For classes, the __repr__() method can be overridden to change the default behavior.
use of repr()
The repr() function can be used to yield a printable representation of the given object. Later the string can be turned into an object with the same values using the eval() function.
# use of repr() and eval()
class Dog:
name = 'rex'
rex = Dog()
rex_printable = repr(rex)
print(rex_printable)
The object rex is turned into the printable representation.
