文件处理

1. 字符串转换成字典

import json
user_info= '{"name" : "john", "gender" : "male", "age": 28}'
user_dict = json.loads(user_info)
user_dict
# {u'gender': u'male', u'age': 28, u'name': u'john'}

 

2. 使用csv写入文件

import csv
f = open("./data/api.csv",'w+',encoding='utf8',newline='')
writer = csv.writer(f)
writer.writerow([
    "Device Specific",
    "Restricted Access ( Requires Provider Approval )",
    "SSL Support"
])
f.close()

3 去除首位指定字符

str1 = "\n   123 123    \n"
str1.strip("\n").strip(" ")

>>>'123 123'

 

4 去除指定字符串

import re
str1 = "\n\t\r 123 \n\t\r111"
re.sub('[\r\n\t]','',str1)
>>>' 123 111'
