需求

讀取mysql下的mysql.ini配置檔案，並講配置檔案轉化為字典並採用不同方法進行序列化

程式碼實現

# -*- coding: UTF-8 -*-
import configparser
import json
import pickle

def series(filename,sdump=pickle.dumps):
    """
    This function is to serieation a object
    sdump=pickle.dumps or sdump=json.dumps
    """
    cfg = configparser.ConfigParser()
    cfg.read(filename)
    ini_dict = {}

    for
 
 k in cfg.keys():
        dictkv = {}
        for key,val in cfg.items(str(k)):
            dictkv[key] = val
        ini_dict[k] = dictkv

    with open('test','wb') as f: #序列化儲存到磁碟
        #f.write(str(series('mysql.ini',sdump=pickle.dumps)))
        pickle.dump(ini_dict,f)

    j = sdump(ini_dict)

    return
 
 type(j),j

print(series('mysql.ini',sdump=pickle.dumps))
#print(series('mysql.ini',sdump=json.dumps))
執行結果：
(<class 'bytes'>, b'\x80\x03}q\x00(X\x05\.......)

程式碼優化

優化思路

• 在ini配置檔案中本身是巢狀字典，因此在生成字典時

for k,v in cfg.items():
        ini_dict[k] = dict(cfg.items(k))

程式碼實現

# -*- coding: UTF-8 -*-
 

import configparser
import json
import pickle
import argparse

def series(filename,sdump=pickle.dumps):
    """
    This function is to serieation a object
    sdump=pickle.dumps or sdump=json.dumps
    """
    cfg = configparser.ConfigParser()
    cfg.read(filename)
    ini_dict = {}

    #method1
    #for k in cfg.keys():
    #    _d = {}
    #    for key,val in cfg.items(str(k)):
    #        _d[key] = val
    #    ini_dict[k] = _d

    #method2
    for k,v in cfg.items():
        ini_dict[k] = dict(cfg.items(k))

    with open('test','wb') as f:
        pickle.dump(ini_dict,f)

    j = sdump(ini_dict)

    return type(j),j

print(series('mysql.ini',sdump=pickle.dumps))
#print(series('mysql.ini',sdump=json.dumps))
