How to return None if Dictionary key is not available?

Question

I need a way to get a dictionary value if its key exists, or simply return None, if it does not.

However, Python raises a KeyError exception if you search for a key that does not exist. I know that I can check for the key, but I am looking for something more explicit. Is there a way to just return None if the key does not exist?

Hello @kartik,

You should use the get() method from the dict class

d = {}
r = d.get('missing_key', None)

This will result in r == None. If the key isn't found in the dictionary, the get function returns the second argument.

Thank you!!
