Adding "for" loop results inside a "logger" message-CodePudding

I have the following function logic.

def funct(arg):
    ...
    return result_list

param_list = ['param1','param2']
for my_arg in param_list
    my_results = funct(my_arg)

How do I get the full list of results for running the function on both parameters? Is there a better way to organize this?

CodePudding user response：

Make my_results a list, and extend it on each call.

my_results = []
for my_arg in param_list
    my_results.extend(funct(my_arg))

CodePudding user response：

If you want a single message, create a dictionary mapping the inputs to the outputs and pack it all at once

Beware very large dicts can be troublesome and you may want to truncate it, base64-encode it, or do other work to reduce the result size

results = {}
for my_arg in param_list
    results[my_arg] = funct(my_arg)

logger.info(f"results mapping: {results}")

CodePudding user response：

This is a rare case where you may actually want generator delegation, which could make your functions much more efficient (as they can avoid creating intermediate lists, which are only discarded)

def funct(input_value):
    for result in some_source(input_value):
        yield result

def funct_wrapper(input_values):
    for input_value in input_values:
        yield from funct(input_value)

Collect and use the results, adding them to some collection to display later

CodePudding user response：

Make my_results as list append or extend it on each iterations  , 
example  enter code here`mentioned below:

def funct(arg):
    ....
    return result_list
my_results=[]
param_list = ['param1','param2']
for my_arg in param_list:
    my_results.append(funct(my_arg))
# print(my_results)
