i am trying to create a dictionary like something below:
frnd_detail1 = {
{'name':'AD', 'age': 30}, {'name':'AKB', 'age':90}, {'name':'SD', 'age':40}
}
but i am getting the below error message as:
File "<ipython-input-72-a0d88fef112d>", line 4, in <module>
{'name':'SD', 'age':40}
TypeError: unhashable type: 'dict'
why it is so, please provide some details
You are creating a set (by accident I guess) by surrounding your dictionaries with curly braces {}.
In Python you can create sets using {} like this:
>>> my_set = {1,2,3}
>>> print(type(my_set))
<type 'set'>
Sets can only have values that are hashable. A dict isn't hashable which is why you get the error. You might want to create a list instead by replacing your outer {} with [] like this:
frnd_detail1 = [{'name': 'AD', 'age': 30}, {'name': 'AKB', 'age': 90}, {'name': 'SD', 'age': 40}]
I guess you want to create a dictionary of dictionaries or list of dictionaries.
If its a dict of dicts, then you need to give a key for its value, and not just ut each dictionary independently.
If its a list of dicts, you can append each dict into a list.
