Use itertools.cycle() to make an iterator that goes round-and-round. Use
itertools.izip() to match it up with your data, and perhaps a set of colors,
too.
import itertools
def marker_cycle():
""" Return an infinite, cycling iterator over the available marker symbols.
This is wrapped in a function to make sure that you get a new iterator
that starts at the beginning every time you request one.
"""
return itertools.cycle([
'o','^','v','<','>',
's','+','x','D','d',
'1','2','3','4','h',
'H','p','|','_'])
for kk, m in itertools.izip(range(A.shape[0]), marker_cycle()):
loglog(f, A[kk], linestyle='-', marker=m, lw=2)
