I personally saw how novice Python programmers searched for “Python compiler” while their actual intent was to find Python REPL/execution environment online (pythontutor, ideone, repl.it, trinket.io, etc)
Many of this services use “compiler” in their description. It may be technically true if they use Python implementation that compiles Python source to byte code first, and then interprets the resulting bytecode (like CPython, Pypy implementation do).
Those who actually want to produce binaries from their Python scripts, which this doesn't do.
