multiline inline anonymous functions in python

>>> from fonc import fonc
>>> [
...     fonc("""
... def x(input): # doesn't matter what this function is called
...     value = input * 3.14
...     return int(value)
...     """)(value) for value in [1, 2, 3, 4]
... ]
[3, 6, 9, 12]

why would you do this terrible thing

:) :) :) :) :) :) :) :) :) :) :) :)

does this pollute my global namespace?

nope!

imagine this inline function:

>>> from fonc import fonc
>>> [
...     fonc("""
... def x(input): # doesn't matter what this function is called
...     value = input * 3.14
...     return int(value)
...     """)(value) for value in [1, 2, 3, 4]
... ]
[3, 6, 9, 12]

One might imagine that this means that the x function name is overwritten to the global namespace. It is not!

>>> x(1)

NameError: name 'x' is not defined

how this works pls?

• parse the string and determine the name of the defined function
• replace that with a known random value
• replace calls to that inline function with calls to the renamed function

never-asked questions

• Do I have access to global vars inside this function?

  ya

• Can I use this in production?

  absolutely not u fool
