Q2.py

# Write a code snippet that inputs a sentence from the user, then uses a dictionary to summarize the number of occurrences of each letter. Ignore case, ignore blanks and assume the user does not enter any punctuation. Display a two-column table of the letters and their counts with the letters in sorted order.

# ```
# Example
# Input >>> "This is a sample text with several words This is more sample text with some different words"
# Output >>>
# [('a', 4), ('d', 3), ('e', 10), ('f', 2), ('h', 4), ('i', 7), ('l', 3), ('m', 4), ('n', 1), ('o', 4), ('p', 2), ('r', 5), ('s', 10), ('t', 9), ('v', 1), ('w', 4), ('x', 2)]
# ```
