Answer 1

To change the axes range, you can use

plt.xlim([-3, 3])
plt.ylim([-3, 3])

You will then have to remove the line plt.axis('scaled') for this to work.

import numpy as np
import matplotlib.pyplot as plt
import scipy, pylab

plt.axes()
circle=plt.Circle((0, 0), radius=1, fc='w')
plt.gca().add_patch(circle)
plt.xlim([-3, 3])
plt.ylim([-3, 3])
plt.yticks(np.arange(-3, 3, 0.25))
plt.xticks(np.arange(-3, 3, 0.25))
plt.show()

Use first xticks and yticks before xlim and ylim. This will create an array before it sets the limit
