Python printing the word

Question

If any one can help me with Python code: If I input a letter, How can I print all the words start with that word?

Answer 1

There are many ways of doing this, e.g.:

words = ["zwei", "peanuts", "were", "walking", "down", "the", "strasse"]
letter = "w"
output = [x for x in words if x[0] == letter]

The contents of output will be:

['were', 'walking']

Some notes:

• If the code needs to be fast you should put the wordlist in some kind of tree.
• If you need more flexibility, you should build a regular expression for matching

Answer 2

print [word for word in words if word.startswith(letter)]
