[Style] Use isinstance() rather than type() for a typecheck.

[Zerohertz]

Problem Definition

Use isinstance() rather than type() for a typecheck. The idiomatic way to perform an explicit typecheck in Python is to use isinstance(x, Y) rather than type(x) == Y, type(x) is Y. Though there are unusual situations where these give different results.
