I want to create a dict like this from input in python-CodePudding

all the contents must be inserted from the input

graph={
'A':{'B':3,'C':4},
'B':{'A':3,'C':5},
'C':{'B':5,'D':'1'},
'D':{'C':1},
}

CodePudding user response：

Take the input in JSON format and then you can easily use json.loads to convert it to a dictionary.

>>> import json
>>> graph = json.loads(input("Enter graph as JSON: "))
Enter graph as JSON: {"A":{"B":3,"C":4},"B":{"A":3,"C":5},"C":{"B":5,"D":"1"},"D":{"C":1}}
>>> import pprint
>>> pprint.pprint(graph)
{'A': {'B': 3, 'C': 4},
 'B': {'A': 3, 'C': 5},
 'C': {'B': 5, 'D': '1'},
 'D': {'C': 1}}

def make_dict():
    d = {}
    while True:
        key = input("Enter the key of dict: ")
        if key == "": // just stay blank to out from func
            break
        ch = input(f"Do you wanna to create nested dict for the key{key}? [y / <Press Enter for No>]")
        if ch == "y":
            value = make_dict()  // use recursion
        else:
            value = input(f"Enter the value for the key {key}: ")
        d[key] = value
    return d


print(make_dict())
