如何根据用户的输入为字典分配名称

Question

我们如何为字典指定一个取自用户输入的名称，并将该字典保存到一个 txt 文件中，以便我们可以按名称搜索它并将输出打印给用户？我现在在这里：

有什么想法吗？

import sys
import pathlib
'''Arg-V's should be in following order <app.py> <action> <nick_name> <name> <phone> <email>'''

if str(sys.argv[1]).lower == 'add':
    current = {'Name': sys.argv[3], 'Phone Number': sys.argv[4], 'Email': sys.argv[5]} 
    with open('contacts.txt', 'w') as f:
        f.write(current)

根据Naming Lists Using User Input：

An indirect answer is that, as several other users have told you, you don't want to let the user choose your variable names, you want to be using a dictionary of lists, so that you have all the lists that users have created together in one place.

import json

name = input('name/s of dictionary/ies : ')


names = {}

name = name.split()

print(name)

for i in name:
    names[i]={}

print(names)

for i in names:
    print(i,'--------->', names[i])

for i in names:
    names[i] = '1'*len(i)
for i in names:
    with open(i+'.txt', 'w+') as file:
        file.write('prova : '+json.dumps(names[i]))
