What are the differences between Python Dictionaries vs Javascript Objects?

Question

I\'m new to python and I was reading about Dictionaries. And from my previous experience with langages like javascript they seemed like objects to me. Dictionaries can store

Answer 1

Keys in Python dictionaries must be hashable (e.g. a string, a number, a float), while JavaScript does not have such a requirement. Consider this example:

The following is a valid object in JavaScript:

const javascriptObject = { name: 'Alexander Pushkin', year: 1799 }

However, it would be invalid as a Python dictionary:

python_dictionary = {name: 'Alexander Pushkin', year: 1799}


# Results in a NameError: name 'name' is not defined

A quick fix would be to convert the Python dictionary's keys into strings:

my_dictionary = {'name': 'Alexander Pushkin', 'year': 1799}
