This method allows for additional initialization logic to be performed after the object has been created, making it ideal for setting default values from a dictionary. fromdataclassesimportdataclass,field @dataclassclassMyClass:field1:str field2:int=field(default=0)def__post_init__(self):ifnotha...
Observe that the structure of the dictionary and the JSON object are almost the same. Dictionary to JSON File in Python To convert a dictionary to a JSON file, we can use the dump() method. The dump() method takes the python dictionary as its first input argument and a file pointer to...
