title: Regex for weekdays in python
body: <p>I seem to be having a problem finding the correct regex for weekdays in Python. I have tried this: </p>
  
  <p>/(mon|tues|wednes|thurs|fri|satur|sun)day/</p>
  
  <p>The problem is that this regex accepts if I just have "mon" in a text, but I only want it to accept if I have "monday". How do I fix this? I can't seem to understand how to do this. </p>
