python收集多个函数的返回值，并在一个非主函数处针对所有函数验证输入

Question

I am looking for solution where I can make sure that input value tested against each function and returned for all error case.

Here is my code.

def func_a(value):
   do something
   return

def func_b(value):
    do something
    return

def func_c(value):
    do something
    return

def final(value):
    A=def_a(value)
    B=def_b(value)
    C=def_c(value)
    if A != foo:
      return A
    elif B != foo:
      return B
    elif C != foo:
      return C
    else:
       return'Success'

    main()

       print final(value)

Problem:

I passing one file as a value where each line should be tested against certain test. Now if there is a issue in line which matches to def_a(), the def_a() will be executed but that line did not tested against remaining functions(fund_b, fund_c) due to if loop in def final().

Question:

Is there a way , I can craft a def final() such a way that each line tested for all functions and if that line match with more than one function then both conditions will be executed?

Answer 1

Store the function results in a dictionary and return it as needed:

def final(value):
    result = {'A':def_a(value),
              'B':def_b(value),
              'C':def_c(value)}
    if any(item != foo for item in result.values()):
      return result
    else:
       return'Success'
