Error when plotting using Matplotlib

[DaRobba]

Hi,

I get the following error with this piece of code:

Does anyone have any ideas as to what I'm doing wrong. Please note I am totally and completely new to Python programming.

Thank you

import matplotlib.pyplot

plt.plot([1,2,3,4],[4,7,8,12]   )

plt.ylabel('some numbers')

plt.show()

Hi DaRobba,

You have a small error in your first line :

import matplotlib.pyplot as plt

plt.plot([1,2,3,4],[4,7,8,12]   )
plt.ylabel('some numbers')
plt.show()

The error is in  the import line itself.
I also am getting this error. It is telling that installing the "six" module will solve this, but after installing six module also, I am getting this error
