In Python, all objects produce two string representations:

+ + +
  • The str is legible to humans. +
    • +
  • The repr is legible to Python +interpreter.
    • +     + + + +
  • +

    repr: Provides a string +representation that can be used to recreate the object. It's designed +for debugging and introspection. It aims for a more precise and +detailed description, often including the object's type.

    +

    Examples:

    + +class MyClass: + def __init__(self, value): + self.value = value + def __repr__(self): + return f"MyClass({self.value})" +obj = MyClass(10) +print(repr(obj)) # Output: MyClass(10) + +
    • + +
  • +

    repr: Provides a human-readable +string representation of the object. It's designed to be easily +understood by humans.

    +

    Examples:

    + +class MyClass: + def __init__(self, value): + self.value = value + def __str__(self): + return f"MyClass with value: {self.value}" +obj = MyClass(10) +print(str(obj)) # Output: MyClass with value: 10 + +

    Certain names are special because they have built-in behavior.

    These names always start and end with two underscores.

    + + +
  • __init__ Method invoked +automatically when an object is constructed
    • +
  • __repr__ Method invoked +to display an object as a Python expression
