title: I want to remove multiple characters from a string input by user
body: <p>I am trying to ask the user for their phone number, and many people type their number such as "123-456-7890", "(123)456-7890". </p>
  
  <p>I want to make the program strip the " ()- " from the input so that when I print the number back to the user, it shows it as 1234567980 without all the extra characters.</p>
  
  <p>So far I have been able to remove only the first parentheses from the string by doing this:</p>
  
  <pre><code>number = str(input("Enter phone number: "))
  print(number.strip('('))
  </code></pre>
