myfile= open('filename.txt')
myfile.read() # reads a string of everything in the file
myfile.seek(0) # reset the cursor to the top of the file
contents = myfile.read()
myfile.readlines() # will read lines as a list
myfile.close() # closes the file
with open('filename.txt') as my_new_file:
 contents = my_new_file.read()
