Python str versus unicode

In Python, the __str__ and __unicode__ methods are special methods used to customize the string representation of an object. However, there is a key difference between the two: __str__ is used in Python 3 and newer versions, while __unicode__ is used in Python 2.
Here, I will provide a tutorial that explains the purpose and usage of __str__ in Python 3, along with code examples. If you are working with Python 2, you should use __unicode__ instead.
The __str__ method is used to define the string representation of an object when using built-in functions like str(). It allows you to provide a human-readable representation of your object. The __str__ method should return a string.
Here's how to define and use __str__ in a Python class:
In this example, the __str__ method is defined within the MyClass class, and it returns a string representation of the object. When we use str(obj), it calls the __str__ method to obtain a string representation.
It's important to note that the __str__ method is used for display purposes and should aim to provide a clear, user-friendly representation of the object.
In Python 2, the __unicode__ method is used instead of __str__. It serves the same purpose but returns a Unicode string. Python 2 is no longer supported, and Python 3 has become the standard, so you should use __str__ in Python 3.
Here's how to define and use __unicode__ in Python 2:
In Python 3 and newer versions, you should use the __str__ method to define a human-readable string representation of your objects. The __str__ method is used with built-in functions like str() to obtain the string representation. In Python 2, the equivalent method is __unicode__, but it's important to note that Python 2 is no longer supported, and it's strongly recommended to upgrade to Python 3 for ongoing development.
