python中for循环嵌套执行顺序_python while循环

I wish to do the following:

1) Try a variety of input combinations to search for a best result

2) Reset all arrays as they were before each loop of the code

Every variable I am working with is in an array such as f[0,1,2,3,…]

The issue is likely in the resetting variables after each pass part, as the first pass works fine, but the residuals of the first pass cause the following iterations to break early..

Here is the pseudo for my method. So very simple, likely an issue with how Python handles data (object oriented)..

index_save = index

for input1 in [0.1,0.2,0.3,…]

for input2 in [10,20,30,…]

for input3 in [-0.1,-0.2,-0.3,…]

index = index_save #To reset the index and thus all arrays

while True:

index = index + 1

f[index] = *Function of inputs*

result = *Function of f and inputs*

if condition_met = true

break

if result > result_best

result_best = result

inputs_best = [input1,input2,input3]

解决方案

It turns out the answer to my question is as follows.

Using nested for loops to brute force combinations works (obviously). Using the method I outlined in the question works to do so. The part that requires care, is making sure you have successfully reset all variables on each pass. That means variables that are integers will have to be reset manually. This is in contrast to how I could reset all arrays simply by resetting the index.

integer_save = integer

index_save = index

for input in range

index = index_save

integer = integer_save

index = index + 1

array[index] = (physics functions based on input)

integer = (physics functions based on input)
