reading, modifying and writing json file

[metalray]

Hi Python Experts,

I am trying to open a json file, modify the content and write it to a different directory.
The code runs but nothing is really happening.

I am not sure what should come first, the dump or the misc save. Is the dump a save as well?

from scipy import ndimage, misc
import numpy as np
import os
import cv2
import json

def main():
    outPath='C:/..../'
    path='C:/...../data_aug_test/'

    # iterate through the names of contents of the folder
    for file_path in os.listdir(path):
	
	#create the full input path and read the file
        input_path = os.path.join(path, file_path)
	
        if file_path.endswith('.jpg'):	

             print('jpeg process')
		
    else: #.json
         print('else json handling')
		 
         with open(input_path, 'r') as f:
             data = json.load(f)
             data['id'] = 134 # <--- modify value.
			 
		    #write file then save	 
             jsonsavepath = os.path.join(outPath, 'flipped_'+file_path)
             misc.imsave(jsonsavepath, f)
			 
         with open(input_path, 'w') as f:
             json.dump(data, f, indent=4)	 
		 
if __name__ == '__main__':
     main()
