how do i use get for my histogram function?

[buran]

get is for java in python use:

value = your_dict[your_key]

Larz, OP means
dic.get(key[,defualt]) method

@OP: what it does is to return default value if key is not present in the dict. If you don't use it, in this case you will get KeyError. So it's a nice way to return default value instead of getting error.
Now, think how you can replace the if statement using dict.get()
