Define Python function in Julia file with PythonCall?

Whenever you use pyexec you’re invoking the Python parser, which makes for an unfair comparison. It’s better to use it to create a Python function then call that: @pyexec """ def fib(n): a, b = 0, 1 while a < n: print(a, end=' ') a, b = b, a+b print() """ => fib fib(10) This example uses @pyexec’s handy => notation for getting variables into and out of Python.
