Simplifying a rather short code

[nilamo]

Instead of 10 functions, I'd just have one. Then just have one variable full of all the circles.

def f(num, x):
    return (num/10) * np.exp(x*1j)

circles = []
for i in range(1, 11):
    circles.append([
        [f(i, n).real for n in np.linspace(0,2*np.pi,1000)],
        [f(i, n).imag for n in np.linspace(0,2*np.pi,1000)]
    ])

for circ in circles:
    plt.plot(*circ)

plt.show()

Or, you can skip the intermediary variable(s):

for i in range(1, 11):
    plt.plot(
        [f(i, n).real for n in np.linspace(0,2*np.pi,1000)],
        [f(i, n).imag for n in np.linspace(0,2*np.pi,1000)]
    )
plt.show()
