python3中json.dump()与json.dumps()的区别
1.json.dump()是通过文件的形式进行处理，举个栗子：
1 import json
2
3 my_dict = dict()
4 with open('labels.txt', 'r', encoding='utf-8') as f:
5 contents = f.readlines()
6 for content in contents:
7 key = content.split(':')[0]
8 label_1 = content.split(':')[1].split(',')[0]
9 label_2 = content.split(':')[1].split(',')[1]
10 value = [label_1, label_2]
11 my_dict[key] = value
12
13 with open('./filename.json', 'w', encoding='utf-8') as f:
14 json.dump(my_dict, f)
label.txt内容如下：
2:'地地意同了H', 'rreree'
4:'3YP65G', 'ybbreb'
2.json.dumps()是将字典转换为json，不通过文件，举个栗子
import json
data = {
'name' : 'soap',
'shares' : 90,
'price' : 542.23
}
json_str = json.dumps(data)
