Python 批量处理JSON文件，替换某个值

直接上代码，替换key TranCode的值 New 为 Update。输出 cancel忽略

import json
import os
import io

path = 'D:\\Asics\\850\\202307'  # old
path2 = 'D:\\test2'  # new
dirs = os.listdir(path)
num_flag = 0
for file in dirs:  #
    if os.path.splitext(file)[1] == ".JSON":  #
        num_flag = num_flag + 1

        with io.open(os.path.join(path, file), 'r', encoding='utf-8') as load_f:
            load_dict = json.load(load_f)
        n = len(load_dict['Orders'])
        Orders = load_dict['Orders']
        OrderLines = Orders[0]['OrderLines']
        SKUs = OrderLines[0]['SKUs']
        flag=False
        for i in SKUs:
            if i['TranCode'] == 'New':  # error
                i['TranCode'] = 'Update'  # true
            if i['TranCode'] != 'Cancel':
                flag=True
        if(flag):
            with io.open(os.path.join(path2, file), 'w', encoding='utf-8') as dump_f:
                dump_f.write(unicode(json.dumps(load_dict,dump_f, ensure_ascii=False)))

if (num_flag == 0):
    print('Sorry no files')
else:
    print('release{} number json files'.format(num_flag))
