You can set the formatter for the yaxis
from matplotlib.ticker import FormatStrFormatter
fmt = FormatStrFormatter('%1.4g') # or whatever
ax.yaxis.set_major_formatter(fmt)
There is also a class tickers.ScalarFormatter for scientific
formatting that is customizable. You'll probably want to take a look
at it.

The easiest way to fix this is just to move the left border of your
axes over a bit
fig = figure()
fig.subplots_adjust(left=0.2)
ax = fig.add_subplot(111) # now there is more space on the left
