i think this should work out. follow the following syntax, and modes, now i think u'll able to read it.
open(filename, mode)-->returns file object
modes--> 'r' read
'w' write
'a' append
'r+' R/W
'b' append this to any of the above to open the binary file.(allowed only in Windows)
>>> f=open('/tmp/workfile', 'w') >>> printf
#this will print whole file content.
following are the other options which u may need.
fileobj.read(no. of bytes) if no. of bytes is not specified then defaultly reads the whole file.
.readline(no. of bytes)--> reads the file in line-by-line and returns a list containing lines as the item of list.
returns empty string if the end of file is reached.
.write(string/variable)--> if EOF is reached returns None
.tell()--> tells the current position of the file pointer.
.seek(offset, from-what)--> moves the file pointer to offset + from-what position, if from-what is not specified then fp is seek from start.
.close()
