Automatic code generation in python

Question

I need to call functions in a C dll from python. So I need to write functions of the format

def funcA(self):
    ans = ctypes.uint64()
    self.driver.getA(ctypes.byref(ans))
    return ans

now I have to write the same code about 30 times, the only difference in each being the name of function called funcA , funcB , funcC and similarly the dll function getA, getB, getC and the type of the return values which can vary

typically I could like to just have a dict

funcs = { 'A':'uint64', 'B':'bool'}

and automatically generate functins

funcA and funcB , with almost the same structure as shown on top , except for the types and the variable names. I would guess there would be some libraries for it.

Answer 1

Why use strings rather than the types themselves?

funcs = { 'A':ctypes.uint64, 'B':bool }

Then:

def make_func(name, ctype):
    def func(self):
        ans = ctype()
        getattr(self.driver, 'get'+name)(ctypes.byref(ans))
        return ans
   func.__name__ = 'func'+name
   return func

for a, b in funcs.items():
    globals()['func'+a] = make_func(a, b)

Or ditch the dict and for loop and:

funcA = make_func('A', ctypes.uint64)
funcB = make_func('B', bool)
