Preamble setup¶

Introduction¶

The hcn.preamble module is a one-line shortcut to a ready-to-use scientific Python environment.

Usage¶

By calling from hcn.preamble import *, you get:

Category	Imported Names
Scientific	np (numpy), plt (matplotlib.pyplot)
Math	pi, e
Utilities	os, sleep (time.sleep), tqdm
Styling	Pre-configured MATLAB-style plotting

Examples¶

In [1]:

from hcn.preamble import *

from hcn.preamble import *

In [2]:

print(f"pi: {pi}")
print(f"e: {e}")

print(f"pi: {pi}") print(f"e: {e}")

pi: 3.141592653589793
e: 2.718281828459045

In [3]:

x = np.linspace(0, 2*pi, 128)
plt.plot(x, np.sin(x))
plt.show()

x = np.linspace(0, 2*pi, 128) plt.plot(x, np.sin(x)) plt.show()

In [4]:

x, y = np.meshgrid(np.linspace(-3, 3, 128), np.linspace(-3, 3, 128))
rho = np.sqrt(x**2 + y**2)

plt.imshow(np.exp(-rho**2))
plt.show()

x, y = np.meshgrid(np.linspace(-3, 3, 128), np.linspace(-3, 3, 128)) rho = np.sqrt(x**2 + y**2) plt.imshow(np.exp(-rho**2)) plt.show()
