How to parse a dictionary items in Python?-CodePudding

I have below file

file.py

data = {
    "SerialNumber": 1234,
    "ActualCount": "TY"
}

In app.py I can easily import this file and can call the dictionary like below:

app.py

import file as file

print(file.data['SerialNumber'])

Is there any type of parser available which can parse this dict objects and then we can get its items like below:

print(file.data.SerialNumber)
print(file.data.ActualCount)

CodePudding user response：

If you really want this, you can implement your own dict class supporting __getattribute__ method, rough example:

data = {
    "SerialNumber": 1234,
    "ActualCount": "TY"
}


class MyDict(dict):
    def __getattribute__(self, item):
        return self[item]


my_dict = MyDict(data)

print(my_dict.SerialNumber) # 1234

CodePudding user response：

if you need this behavior you can also try namedtuple:

from collections import namedtuple

data = {"SerialNumber": 1234, "ActualCount": "TY"}

MyDict = namedtuple('MyDict', data.keys())
my_dict = MyDict(**data)

print(my_dict.SerialNumber)  # 1234
print(my_dict.ActualCount)  # TY
