Using a dict comprehension with all of your chosen letters will give you key:value pairs with 'lower':'UPPER'.

lower_to_upper = {
    letter: letter.upper()
    for letter in 'abcdefghijklmnopqrstuvwxyz'
}

Use a list comprehension to build tuples that are input to create the dictionary.

mylist = ['a', 'b', 'c']
dict((i, i.upper()) for i in mylist)

output

{'a': 'A', 'b': 'B', 'c': 'C'}
