does the following surprise you too ?
f = open("filename")
print f.readline() # prints first line
print f.readline() # prints second line
print f.readline() # prints third line
print open("filename").readline() # prints first line
print open("filename").readline() # prints first line
print open("filename").readline() # prints first line
