info = {'John':111111,'21/may/1998','Mike':'222222','14/feb/1996'}

i don't want to add it manually

Answer 1

好吧，您应该将“约翰”指向一个字典（或创建类来代表您的每个人（？）），因为您试图为他们保留多个代表他们的特征，并且为了使您的数据易于理解，您必须将 json 重构为这样：

info = {'John': {'id': 111111, 'birthday':'21/may/1998'},'Mike':{'id':222222,'birthday':'14/feb/1996'}}

Answer 2

You can store the values as a list or tuple.

info = {'John': [111111], 'Mike': ['222222']}
info_b = {'John':'21/may/1998','Mike':'14/feb/1996'}
for k, v in info.items():
    v.append(info_b.get(k, ''))

info
# returns:
{'John': [111111, '21/may/1998'], 'Mike': ['222222', '14/feb/1996']}

Answer 3

Try making the value of each person a list

info = {"John": [111111], "Mike": [222222]}

count = 0
for item in info.values():
    birthday = input(f"{[*info.keys()][count]}'s birthday:\n")
    item.append(birthday)
    count += 1

print(info)

Answer 4

Dict it's all about key and value.

The best way to perform without using Class is to set the pair key/value for each Person.

Example:

#First you create two different Person
info = [{'name': "John", 'id': 111111}, {'name': "Mike", 'id': 222222}]

#If you want update the birthday of the first Person (John) you can do it like that.
info[0]["birthday"] = "21/may/1998"

#And for Mike you modify the second item in the list 
info[1]["birthday"] = "13/june/1996"
