Text completion

Text completion is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

Task

Write a program that takes in a user inputted word and prints out possible words that are valid in the English dictionary. Please state any dictionaries or files/binaries/dependencies used in your program. Do show the similarity of the inputted word and outcome as a percentage.

Resources

Github Repo
Raw Text, Save as .txt file

Possible Output

Input word: 
complition

compaction : 80.00% similar.
completion : 90.00% similar.
completions : 81.82% similar.
complexion : 80.00% similar.
