python - 没有功能的打印输出

Question

我创建了多个不输出最终数字作为打印的函数，任何人都可以帮忙。谢谢。

strips = int(input('Enter your number of strips: '))
lower = int(input('Enter your lower limit'))
upper = int(input('Enter your upper limit'))

#define Trapzeium rule
def trapezium(function3,lower,upper,strips):
    h=float(upper-lower)/strips
    result=0.5*function3(lower)+0.5*function3(upper)
    for i in range(1,strips):
        result+=function3(lower+i*h)
    result=h*result
    return result

#define function3
def function3(x):
    return 3*(x**2)*exp(x**3)
    trapezium_numerical=trapezium(function3,lower,upper,strips)
    print(trapezium_numerical)
