ValueError: No escaped character for python shlex.split
===

i have a string as follows 
mystring1=xcopy /Q /Y d:\\Program Files\\TestData\\*.* c:\\Program Files\\TestData\\Company name\\
mystring2=xcopy '/Q' '/Y' 'd:\tj\tjData\\' "c:\Program Files\TestData\\Company name\\"

i used shlex module as follows 

    mylist1=shlex.split(mystring1) 
    mylist2=shlex.split(mystring2) 

but iam getting an error 

ValueError: No escaped character

mylist1 value should be **[xcopy,/Q,/Y,d:\\Program Files\\TestData\\,c:\\Program Files\\TestData\\Company name\\]**

and 

mylist2 value should be **[xcopy,/Q,/Y,d:\tj\tjData\\,c:\Program Files\TestData\\Company name\\]**
