Good insight. In fact you don't need to create the variable. The code ``data
= open('filename').read()`` will open the file named "filename" in the
current working directory, read it, and assign the data to a variable.
However, many programmers use variables not because they must, but because
good variable names can make code easier to read. Also, doing less stuff on
a line of code can make that code easier to read.
