you do something like this
file = open('path\to\file', 'r') # r=read,w=write,a=append,etc
print file.readlines() #or you could use file.read()
#or you could read it line by line
print file.readline() #prints first line
print file.readline() #prints second line
It is not important if the glass is half full or half empty.What is important,is who has been drinking from MY glass?!?!?

Not 100% on what your trying to do 7. If your talking about getting user input and outputting to the console window then you looking for the raw_input() function. If not then what are you trying to do with sys.stdin?

python prog.py < mytext.txt
This will read the redirected file:
text = sys.stdin.read()
#Basic printing to stdout
#or useing the file methods

Your code works fine for me:

print "Enter username:"
user = sys.stdin.readline().strip()
