No module named bumpy
Question: i am new mac user and new to python.

i just install python 2.7 and matplotlib and try to run this demo code:

    
    
    """
    Simple demo with multiple subplots.
    """
    import numpy as np
    import matplotlib.pyplot as plt
    
    
    x1 = np.linspace(0.0, 5.0)
    x2 = np.linspace(0.0, 2.0)
    
    y1 = np.cos(2 * np.pi * x1) * np.exp(-x1)
    y2 = np.cos(2 * np.pi * x2)
    
    plt.subplot(2, 1, 1)
    plt.plot(x1, y1, 'yo-')
    plt.title('A tale of 2 subplots')
    plt.ylabel('Damped oscillation')
    
    plt.subplot(2, 1, 2)
    plt.plot(x2, y2, 'r.-')
    plt.xlabel('time (s)')
    plt.ylabel('Undamped')
    
    plt.show()
    

when i click Run -> Run Module i get this error:

    
    
    Traceback (most recent call last):
      File "/Users/mehmetalinadigulec/Desktop/subplot_demo.py", line 4, in <module>
        import numpy as np
    ImportError: No module named numpy
    

i searched for hours but can`t fix it.

i edit my ~/.bash_profile

    
    
    # Setting PATH for Python 2.7
    # The orginal version is saved in .bash_profile.pysave
    PYTHONPATH="/Library/Python/2.7/site-packages:${PYTHONPATH}"
    export PYTHONPATH
    

and result

    
    
    echo $PYHTONPATH
    /Library/Python/2.7/site-packages:
    


Answer: The simply answer would seem to be to install numpy via
<http://www.scipy.org/install.html>
