title: input() vs sys.stdin.read()
body: <pre><code>import sys
  s1 = input()
  s2 = sys.stdin.read(1)
  
  #type "s" for example
  
  s1 == "s" #False
  s2 == "s" #True
  </code></pre>
  
  <p>Why? How can I make <code>input()</code> to work properly?
  I tried to encode/decode <code>s1</code>, but it doesn't work.</p>
  
  <p>Thank you.</p>
