title: searching in text file word list and check all the words that start with each letter I input
body: <p>So far I got this ...</p>
  
  <pre><code>with open('d:\word_list.txt', 'r') as inF: 
  b = input('Enter word: ') 
  for letter in b: 
   for item in inF: 
    if item.startswith(letter): 
     print(item) 
  </code></pre>
  
  <p>If I type "zucaritas", this code only prints those words begining in "z" and not the other letters, the "u", the "c", etc. I want to check all the words from the list that start with each letter I want to type.
  What can I do? By the way, I'm a beginner in python. Thanks</p>
