将下面的matlab代码变成python代码

下面是Matlab代码：

% Define the function
f = @(x) sin(x);

% Define the limits of integration
a = 0;
b = pi/2;

% Define the number of subintervals
n = 10;

% Calculate the width of each subinterval
h = (b - a)/n;

% Calculate the values of the function at each subinterval
x = a:h:b;
y = f(x);

% Calculate the area using the trapezoidal rule
area = h*(sum(y) - (y(1) + y(end))/2);

下面是对应的Python代码：

import math

# Define the function
def f(x):
    return math.sin(x)

# Define the limits of integration
a = 0
b = math.pi/2

# Define the number of subintervals
n = 10

# Calculate the width of each subinterval
h = (b - a)/n

# Calculate the values of the function at each subinterval
x = [a + i*h for i in range(n+1)]
y = [f(x[i]) for i in range(n+1)]

# Calculate the area using the trapezoidal rule
area = h*(sum(y) - (y[0] + y[-1])/2)

请注意，Python中的列表索引从0开始，因此需要将y(1)和y(end)替换为y[0]和y[-1]。此外，需要导入math模块以使用sin函数。
