python - 无法在 python 中格式化 .json 文件

问题描述

我有一个 python 代码（main.py），其中包含一个名为 json 的 python 模块，我想用它以一种舒适的方式存储一些重要的 key=value 对，以后可以使用。问题在于格式（结构）。

main.py文件包含主要代码。output.json文件显示了主文件的输出。expected_output.json文件包含格式（结构），它显示了我想如何存储我的数据（键=值）。

如果有人有兴趣分叉这个存储库，他/她受到了极大的邀请。

代码： main.py


############*****Importing Modules*****############

import random as _random # for making random passwords.
import sys as _sys # for taking command line arguments.
import getopt as _getopt # for making command line flags.
import json as _json


############*****String Decleration*****############

_sm_Letter = ['abcdefghijklmnopqrstuvwxyz'] # small letters to use as a string on the user's password.
_cap_Letter = ['ABCDEFGHIJKLMNOPQRSTUVWXYZ'] # capital letters to use as a string on the user's password.
_sp_char = ['!?,:;()-/@_`~#$%=^+&{*}[]|<>\.'] # special charecters to use as a string on the user's password.
_Numbers = ['0','1','2','3','4','5','6','7','8','9'] # numbers to use as a string on the user's password.
_str = _sm_Letter + _cap_Letter + _Numbers + _sp_char # concatinating those lists
_str = ''.join(_str)
_str = _str*100


############*****Defining Command line Options*****############

_args = _sys.argv[1:] # Remove 1st argument (file name) from the list of command line arguments. 
_s_opt = "ahvl:um:" # short options
_l_opt = ["accounts","help","masterkey=","lenght=","version","update"] # long options


############*****Defining Some Imyportant stuffs*****############

def _usage(): #defining usage
    print ("Usage: "+ _sys.argv[0] + " -m [MASTERKEY]\n")
    print ("Example: "+ _sys.argv[0] + " -m your_master_key\n")
def _help(): #defining help section
    _usage()
    print ("A tool for generate random and strong encrypted password and to keep that password also.\n\nMandatory arguments to long options are mandatory for short options too.")
    print ("-a, --accounts          to know how many accounts are exists.")
    print ("-h, --help          you are now seeing this.")
    print ("-l, --lenght            to pass the lenght of your password.")
    print ("-v, --version           to see the version of this tool.")


############*****Creating Masterkey Genaration Algorithum*****############

def _create_Master_Key():
    _masterKey = _random.sample(_str, 1000)
    _masterKey = ''.join(_masterKey)
    print('\nYour password is : '+_masterKey)



############*****Trying To Get Info From The User From The Command Line Arguments*****############

try:

    # output error, and return with an error code       
    print (str(err))
    print ("Enter -h, --help for help.")
    exit()




############*****Taking Info From The User Manually and generating random password*****############

_info = {}
