title: Is a Regular Expression Faster than using .replace()
body: <p>Would a regular expression be faster than the following Python code?</p>
  
  <pre><code>myStr.replace(","," ").replace("'"," ").replace("-","").replace("_","").replace("["," ").replace("]"," ")
  </code></pre>
  
  <p>Does this mean that the str is being iterated over 6 times(the number of replace() calls)? Would a regular experession be faster or is it the same algorithm/methodlogy?</p>
  
  <p>What would the regular expression of this look like?</p>
