The second remark is that backslash is an escape character for strings in
(almost) all programming languages. You have to do \\ to get a single
backslash, so this works:
xlabel = text('Time (Units of $\\tau$)',(3,-.10), rgbcolor='black', fontsize=30)
Or you can do:
xlabel = text(r'Time (Units of $\tau$)',(3,-.10), rgbcolor='black', fontsize=30)
