Yep.  From the PickAxe :

Mode   Meaning
r      Read-only, starts at beginning of file (default mode).
r+     Read/write, starts at beginning of file.
w      Write-only, truncates an existing file to zero length or creates 
         a new file for writing.
w+     Read/write, truncates existing file to zero length or creates a 
         new file for reading and writing.
a      Write-only, starts at end of file if file exists ; otherwise 
         creates a new file for writing.
a+     Read/write, starts at end of file if file exists ; otherwise 
         creates a new file for reading and writing.
b      (DOS/Windows only) Binary file mode (may appear with any of the 
         key letters listed above).

I'd add that b has no effect whatsoever on other OSes.  (In other words,
you may leave "wb+" and stay platform independent.)
