title: Python dictionary search values for keys using regular expression
body: <p>I am trying to implement to search for a value in Python dictionary for specific key values (using regular expression as a key). </p>
  
  <p>Example:</p>
  
  <p>I have a Python dictionary which has values like:</p>
  
  <pre><code>{'account_0':123445,'seller_account':454545,'seller_account_0':454676, 'seller_account_number':3433343}
  </code></pre>
  
  <p>I need to search for values whose key has 'seller_account'? I wrote a sample program but would like to know if something can be done better. Main reason is I am not sure of regular expression and miss out something (like how do I set re for key starting with 'seller_account'):</p>
  
  <pre><code>#!usr/bin/python
  import re
  my_dict={'account_0':123445,'seller_account':454545,'seller_account_0':454676, 'seller_account_number':3433343}
  
  reObj = re.compile('seller_account')
  
  for key in my_dict.keys():
          if(reObj.match(key)):
                  print key, my_dict[key]
  
  ~ home&gt; python regular.py
  
  seller_account_number 3433343
  seller_account_0 454676
  seller_account 454545
  </code></pre>
