Python全栈开发：configparser模块

#!/usr/bin/env python
# -*- coding;utf-8 -*-
import configparser

# 创建对象
conn = configparser.ConfigParser()

# conn对象具有read功能，打开文件读取文件，放入内存,要保存必须重写
conn.read("ini", encoding="utf-8")

# conn对象的sections作用：在内存中寻找所有的[???]
result = conn.sections()
print(result)

# 从指定的[???]中寻找所有的key
result = conn.options("section2")
print(result)

# 获取指定节点下key的值
result = conn.get("section1", "k1")
result = conn.getint("section1", "k1")
result = conn.getfloat("section1", "k1")
result = conn.getboolean("section1", "k1")
print(result)

# 判断是否存在某个节点
result = conn.has_section("section1")
print(result)

# 判断某个节点下是否存在key
result = conn.has_option("section1", "k1")
print(result)

# 移除某个节点的键值对
result = conn.remove_option("section1", "k1")
conn.write(open("文件名", "w"))  # 参数是一个可写的对象

# 设置某个节点的键值对,涉及到中文要明确编码，否则出现乱码
result = conn.set('a', "k5", "你好吗")
conn.write(open("好看吗", "w", encoding="utf-8"))
