Python's `repr(obj)` method returns a printable representation of an object as a string.

# Examples

The printable representation of a string has a `''` wrapped around it:

``` x = "hello"print(repr(x)) 'hello' ```

The `repr(obj)` method comes in handy when you need to escape special characters such as the new line character (`\n`):

``` x = "\nhello\n"print(repr(x)) '\nhello\n' ```

This is contrast to printing the string directly:

``` x = "\nhello\n"print(x) hello ```

Internally, the `repr(obj)` function is actually calling the `__repr__(self)` method of the object. We can implement this method for our own classes:

``` class Person: def __init__(self, name): self.name = name def __repr__(self): return repr("My name is " + self.name)person_alex = Person("alex")print(repr(person_alex)) 'My name is alex' ```

If you're using Jupyter notebook, evaluating the object directly outputs the `__repr__` like so:

``` person_alex 'My name is alex' ```
