Is there any regular expression in python to find out the space in folder path
===

i have a python strings as below

mystring1="command1 "D:\\The place\\The King\\" "D:\\The place\\The Queen\\" 

mystring2="command1 "D:\\Theplace\\TheKing\\" "D:\\Theplace\\TheQueen\\" 

Is there any regular expression by which we can find out whether a space  exists in the folder path 
ie how can i distingush mystring1 to mystring2 by using a regular expression
