checksum_dict's objects handle the simple but repetitive task of checksumming addresses before setting/getting dictionary values.

pip install checksum_dict

There are only two things you must know...

from checksum_dict import ChecksumAddressDict

d = ChecksumAddressDict()
lower = "0xb47e3cd837ddf8e4c57f05d70ab865de6e193bbb"
d[lower] = True
print(d)
>>> ChecksumAddressDict({'0xb47e3cd837dDF8e4c57F05d70Ab865de6e193BBB': 'hello'})

As you can see, the lowercase key lower was checksummed and both the key and value were added to the dict as you would expect.

We also have a checksummed version of a defaultdict:

from checksum_dict import DefaultChecksumDict

default = int
d = DefaultChecksumDict(default)
print(d[lower])
>>> 0

Although the key was not found in the dictionary, the default, in this case int, was called and returned a 0, just like with a traditional defaultdict!

Okay, now that's about it. I hope you all get immense value from this simple yet powerful tool. Now get out there and let's do some buidling!
