If anyone can help me with the Python code: If I enter a letter, how can I print all the words that start with this word?

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

There are many ways to do this, for example:

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

The content 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 create a regex to match
