用pythonic方式写一个复杂的循环

Question

I have the following Code

import numpy as np
from readers import readerXYZ
import glob 
folder=r'N:\FolderXYZ/*'
D_list=[]
ctr=0

for name in glob.glob (folder):

    Zdata = readerXYZ(name, output_matrix=True) 

    #I Need this counter of the NaNs for future computations
    ctr=ctr+np.count_nonzero(np.isnan(Zdata))    
    a=list(Zdata.shape)
    D_list.append(a)

The program reads from different files stored in the Folder called "FolderXYZ", this is done with an external program called readerXYZ, what I want to store in the lis D_list is the dimensions of each Zdata Matrix, and at the same time count how many NaNs are in total. This code works fine but takes so Long, how can I improve it? thank you

Answer 1

If time is your concern. You can consider processing the list in parallel. Here is a reference for multiprocessing Python how to parallelize loops
