The interactive interpreter is your friend. Call help(file), and you will
get:

class file(object)
 |  file(name[, mode[, buffering]]) -> file object
 |
 |  Open a file.  The mode can be 'r', 'w' or 'a' for reading (default),
 |  writing or appending.  The file will be created if it doesn't exist
 |  when opened for writing or appending; it will be truncated when
 |  opened for writing.  Add a 'b' to the mode for binary files.

plus extra information. 

Take note that the mode is NOT "b". It is "rb".
