python_30期_第15讲【ini方法+yaml方法】

本次学习知识点了解

ini方法

格式要求：文件名结尾以：.ini

类似与键值对 key = value

[section]

option = value

option = value

[section]

option = value

option = value

[section]

option = value

option = value

读取：单个读取

ConfigParse类

1.引入：from configparse import Configparse

2.实例化：conf = Configparse()

3.读取.ini文件：conf.read(fs,encoding="utf-8")

4.通过get方法，获取section下的option的值

1）value = get(section,option) # 字符串

2）boolean: getboolean() # 布尔值

3）int:getint() # 整数

4）float:getfloat() # 符点数

代码格式：

from configparser import ConfigParser
class HandleConfig(ConfigParser):

    def __init__(self,file_path):
        super().__init__()
        self.read(file_path, encoding="utf-8")
conf = HandleConfig(file_path).yaml方法
from configparser import ConfigParser

# 1、实例化
conf = ConfigParser()

# 2、读取配置文件
conf.read("nmb.ini",encoding="utf-8")

# 3、读取某一项配置值：get,全部都是字符串
value = conf.get("log","file_ok")
print(value)
print(type(value))

# 读取出来为布尔值
val = conf.getboolean("log","file_ok")
print(val)

# 获取当前的section
# conf.sections()
s = conf.options("log")
print(s)

# # 写入：set
# conf.set("log","file_name","py303030.log")
# # 写入文件
# conf.write(open("nmb.ini","w",encoding="utf-8"))
yaml方法：
1.安装：pip install pyyaml  
路径1：pycharm-seeting install package  pyyaml
路径2：cmd下 pip install pyyaml
接受的格式：元组，字典 列表
格式：以.yaml结尾
- hello
- world
-
  key: hello
  value: world
name: xiaojian

log:
  name: py30
  level: INFO
  file_ok: False
  file_name: py30.log

mysql:
  user: nmb
  passwd: 123456
#mysql:
#  - xiaojian
#  - 女

import yaml
1.打开文件：open
with open("nmb.yaml",encoding="utf-8") as fs:
    data = yaml.load(fs,yaml.FullLoader)
    print(data)

2.加载文件数据为字典或者列表对象
yaml.load(fs,loader=yaml.FullLoader)
代码格式：
import yaml

with open("nmb.yaml",encoding="utf-8") as fs:
    data = yaml.load(fs,yaml.FullLoader)
    print(data)
    for key,value in data.items():
        print(key)
        print(value)
可以使用小技巧：
用断点方式：使用小计算器写代码调试查看.ini的格式：int/str/folate
用例一:
  user: python30
  password1: 123456
  password2: 123456
  check:  {"code": 1, "msg": "注册成功"}

用例二:
  user: python36
  password1: 123456
  password2: 123456
  check:  {"code": 0, "msg": "该账户已存在"}
用例三:
  user:
  password1: 123456
  password2:
  check:   {"code": 0, "msg": "所有参数不能为空"}
用例四:
  user:
  password1:
  password2: 123456
  check:   {"code": 0, "msg": "所有参数不能为空"}
用例五:
  user: python27
  password1:
  password2:
  check:   {"code": 0, "msg": "所有参数不能为空"}
用例六:
  user:
  password1:
  password2:
  check:   {"code": 0, "msg": "所有参数不能为空"}
用例七:
  user: python26
  password1: 123456
  password2: 12345
  check:   {"code": 0, "msg": "两次密码不一致"}
用例八:
  user: python29
  password1: 12345
  password2: 12345
  check:   {"code": 0, "msg": "账号和密码必须在6-18位之间"}
用例九:
  user: python28
  password1: abcdefghi1234567890
  password2: abcdefghi1234567890
  check:    {"code": 0, "msg": "账号和密码必须在6-18位之间"}
