The Python object model has rich introspection, including functions for determining and comparing types and identity.
- [Instructor] In Python, everything is an object,…so a Type is the same as a Class.…Here in Komodo, I've opened a working copy…of Types.py from chapter three of the exercise files,…and down here on line four I'm going to…create a tuple with five elements.…I'm going to say one, two, three, four, five.…And when I save and run this, you notice that…line five prints a representation of that tuple,…and line six says that the type is class tuple.…
Now, where this starts to get interesting…is when I make this tuple into something else.…We'll change this two, a string that says two,…we'll change to the three to a float,…change the four, we'll just make that a list,…the number four and a string four,…and we'll leave the five alone.…So when I save and run this, now you'll notice…that the string representation printed out on line five…is exactly the structure that I've created there,…and line six still says type tuple.…
But if instead I ask, well what's the type of…that second element, which would be element number one.…
