Note
====
To open a file/file object :

open(filename,mode)

1. filename can be a file or path to a file
2. mode can be any of the following

1. ‘r’ for reading
2. ‘r+’ for reading and writing
3. ‘w’ for writing
4. ‘a’ for appending
5. both read and write modes also have a ‘b’ option for binary reading and writing (‘rb’, or ‘wb’)

s = myFile.read() Will read entire file into a string
s = myFile.read(N) Will read N bytes (1 or more) from file
s = myFile.readline() Will read next line into string until end of line
L = myFile.readlines() Will read entire file into a list of strings
