title: How can I remove multiple characters in a list?
body: <p>Having such list:</p>
  
  <pre><code>x = ['+5556', '-1539', '-99','+1500']
  </code></pre>
  
  <p>How can I remove + and - in nice way?</p>
  
  <p>This works but I'm looking for more pythonic way.</p>
  
  <pre><code>x = ['+5556', '-1539', '-99', '+1500']
  n = 0
  for i in x:
      x[n] = i.replace('-','')
      n += 1
  n = 0
  for i in x:
      x[n] = i.replace('+','')
      n += 1
  print x
  </code></pre>
  
  <h1>Edit</h1>
  
  <p><code>+</code> and <code>-</code> are not always in leading position; they can be anywhere.</p>
