Animation problem of Virgil Stokes.
Since I began the answer sequence, here's a little more. If this
overlaps other answers, I apologize.
About the third parameter
"/frames/ can be a generator, an iterable, or a number of frames."
This makes very little sense to me --- what does "or a number

I am just that good! No, really though, the book focuses only on a subset
of features in Matplotlib, and it does assume that you are some

The reason why you get that error is because you took out the argument from
the call signature. But, FuncAnimation assumes that it can send in at least
one argument. That argument is not optional, even if you aren'
Brendan, good catch, I didn't notice Virgil's confusion earlier. I think
that is a good explanation. I remember getting very confused by all of that
stuff back when I started in Python. I think mostly because I don't know of
any other language that does argument handling like how Python does it. I

The documentation should say "the number", not "a number". This particular
argument expects either a generator, an iterable, or an integer. If none is
given, it will try and figure out something for itself. The integer is used
to create a number generator, and so you effectively have an iterable th

Here's a version that does what I think you want:
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import sys

Hi all,
How do I use animation.FuncAnimation to plot real-life
data from parsing a text file ?
import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation
import sys
import time
import re
x = [] # x
y = [] # y
fig = plt.figure()
ax= f
