If you're using matplotlib, then what you are looking for is plt.savefig(). The documentation is here: http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.savefig

For example:

import matplotlib.pyplot as plt
import numpy as np

# Some random data:
x = np.random.rand(100)

fig = plt.figure(1)         # create a figure instance
ax = fig.add_subplot(111)   # and axes
ax.hist(x)                  # plot the histogram

# plt.show()                # this would show the plot, but you can leave it out 

# Save the figure to the current path
fig.savefig('test_image.png')
