Question

This code is giving me a SyntaxError. Not sure what is wrong.

import numpy as np
from matplotlib.pyplot as plt

x = np.linspace(0., 10, 0.1)  
y = np.sin(x)
plt.plot(x, y);
plt.show();

This is the error message:

  File "<ipython-input-4-b3d93c2fbfde>", line 2
    from matplotlib.pyplot as plt
                            ^
SyntaxError: invalid syntax

Answer 1

Your second line should be:

import matplotlib.pyplot as plt

In addition, note that you don’t need a semi-colon terminator in Python.

Also, the np.linspace call that you use is wrong – it’ll just give you an empty array. Try the following instead:

x = np.linspace(0, 10, num=101)
