"this is my string".myfunction(argument)

This is very simple in javascript. With the keyword this i can access to my string directly. Is that possible with python?

Answer 1

You can inherit from str and define your own methods:

class myString(str):
    def my_method(self, ...):
        # ...

some_string = myString("StackOverflow")

print some_string.count("a") # method from string
print some_string.myMethod(...) # your defined method
