It's strange that you need to separate functions and other variables. I mostly use Racket, but I'm using Python from time to time. I'm using some code like
def something(N, x):
f, g, h = method_1(N)
#f, g, h = method_2(N)
#f, g, h = method_3(N)
return f(x) + g(x) + h(x)
What I mean by "functions" are the ones that need to be translated into English. For example:
印（“你好”）
print("你好")
「印」（“你好”）
印("你好")
The 「」was a design choice that I made so that I can more easily code the translator to differentiate between variables and other names (e.g. functions), with the side benefit of making the code slightly more readable. Spaces I bet can certainly achieve the same level of readability, but would require more complex code. I'll think about implementing that, however.
