Python Lambda

Syntax

sum = lambda x, y: x + y
sum(1, 4)                    # 5
(lambda x, y: x + y)(3, 7)   # 10

Lambdas contain:

• A single expression
• Statements are not allowed

Simple Use Case - a First Order RC Model

import scipy.integrate as integrate
import matplotlib.pyplot as plt
import numpy as np

t = np.linspace(0.0, 10e-3, 1000)

# Parallel RC Model
R = 100
C = 10e-6
v_init = [10]
v = integrate.odeint(lambda v, t: -v/(R*C), v_init, t)

fig, ax = plt.subplots()
ax.plot(t, v)
