Reading and Writing Files: open() a file

#open() returns a file object, and is most commonly used with two arguments: 
#"open(filename, mode)".

f=open('/tmp/workfile', 'w')
print f


# mode can be 'r' when the file will only be read, 
# 'w' for only writing (an existing file with the same name will be erased), 
# 'a' opens the file for appending; any data written to the file is automatically 
#      added to the end. 
# 'r+' opens the file for both reading and writing. 
# The mode argument is optional; 'r' will be assumed if it's omitted.

# On Windows and the Macintosh, 'b' appended to the mode opens the file in binary 
# mode
# so there are also modes like 'rb', 'wb', and 'r+b'.
