configparser模块

配置文件(.ini)

[section1]
k1 = v1
k2:v2
user=egon
age=18
is_admin=true
salary=31

[section2]
k1 = v1

查

import configparser

config = configparser.ConfigParser()
config.read('text.ini')

# 获取sections
res = config.sections()
print(res)  # ['section1', 'section2']

# 获取某一section下的所有option
print(config.options('section1'))  # ['k1', 'k2', 'user', 'age', 'is_admin', 'salary']

# 获取items
print(config.items('section1'))  # [('k1', 'v1'), ('k2', 'v2'), ('user', 'egon'), ('age', '18'), ('is_admin', 'true'), ('salary', '31')]

# 获取某个section单独的元素值
res = config.get('section1', 'user')
print(res, type(res))  # egon <class 'str'>

# 查看标题section1下age的值=>整数格式
res = config.getint('section1', 'age')
print(res, type(res))  # 18 <class 'int'>

# 查看标题section1下is_admin的值=>布尔值格式
res = config.getboolean('section1', 'is_admin')
print(res, type(res))  # True <class 'bool'>

# 查看标题section1下salary的值=>浮点型格式
res = config.getfloat('section1', 'salary')
print(res, type(res))  # 31.0 <class 'float'>

增删改

import configparser

config = configparser.ConfigParser()
config.read('text.ini')

# 删除整个标题section2
config.remove_section('section2')

# 删除标题section1下的某个k1和k2
config.remove_option('section1', 'k1')
config.remove_option('section1', 'k2')

# 判断是否存在某个标题
print(config.has_section('section1'))

# 判断标题section1下是否有user
print(config.has_option('section1', 'user'))

# 添加一个标题
config.add_section('section3')

# 在标题section3下添加name=egon,age=18的配置
config.set('section3', 'name', 'egon')
config.set('section3', 'age', '18')

# 最后将修改的内容写入文件,完成最终的修改
config.write(open('a.cfg', 'w'))
