A variable in Python is just a name. It has no type.
Only values have types. So you can set (or change)
the type of a value but not of a variable.

There is no shortage of typing in Python its just
applied to the values(objects) not to their labels.

The same applies in Python. You just have to separate
the concepts of variable name and variable value.
In C those two concepts get kind of squished together
but in Python the name/value duality is strong.

You can always check the type of an object by using
the type() function or if you think a type error is
likely catch it when it happens with:

try:...
except TypeError:....
