Case insensitive dictionary

Question

I\'d like my dictionary to be case insensitive.

I have this example code:

text = \"practice changing the color\"

words = {\'color\': \'colour\',
            


        

Answer 1

I just set up a function to handle this:

def setLCdict(d, k, v):
    k = k.lower()
    d[k] = v
    return d

myDict = {}

So instead of

myDict['A'] = 1
myDict['B'] = 2

You can:

myDict = setLCdict(myDict, 'A', 1)
myDict = setLCdict(myDict, 'B', 2)

You can then either lower case the value before looking it up or write a function to do so.

    def lookupLCdict(d, k):
        k = k.lower()
        return d[k]

    myVal = lookupLCdict(myDict, 'a')

Probably not ideal if you want to do this globally but works well if its just a subset you wish to use it for.
