how can I plot string vs float in python?

Question

How can I plot string versus float type graph using pylab?

x = ['PARIS','LONDON']

y = [2.39, 3.41]

how can I plot x versus y?

You need to assign the horizontal relationship to the values of y and then assign your strings as ticks. — Myles Baker

Many thanks to Myles Baker, here is the solution:

import pylab as pl
x = [0,1]
xTicks = ['LONDON','PARIS']
y = [2.39, 3.41]
pl.xticks(x, xTicks)
pl.xticks(range(2), xTicks, rotation=45) #writes strings with 45 degree angle
pl.plot(x,y,'*')
pl.show()

Is there an equivalent way to do this for a single axes? I tried ax.set_xticks() and ax.set_xticklabels(), and they seemed to be ignored...
