title: Convert number from 15.5K and 1.20M to 15.500 and 1.200.000, python
body: <p>I am new in python and im trying to convert the list 
  L =["11.4K" , "550" , "1.23M" , "30"]<code>to : 
  L=["11400" , "550" , "1230000" , "30"]</code>
  I believe that K means 1000 and M means 1000000</p>
  
  <p>Note: what if only one number in the list is in the form of K or M and what happens if the position of displayed numbers <code>( K, M )</code> will not remain in the same place of the list. 
  eg: what happens in this case: <code>L1=[23 , 9.7K , 34 , 900]</code> 
  convert to : <code>L1=[23 , 9700 , 34 , 900]</code></p>
