请用python语言编写如下片段：Download the data drx-sample1.xy, drx-sample2.xy, drx-sample3.xy,drx-sample4.xy and drx-sample5.xy and place them on your current python working directory.Read these data with your favorite text editor.Then,Open the first file and push data in numpy.array for plotting X-ray diffraction diagram.ou should obtain something like.

以下是使用Python编写的片段：

import numpy as np
import matplotlib.pyplot as plt

# Download the data files and place them in the current working directory
# Read the data files with your favorite text editor

# Open the first file and push data into a numpy array for plotting the X-ray diffraction diagram
data = np.loadtxt('drx-sample1.xy')
x = data[:, 0]
y = data[:, 1]

# Plot the X-ray diffraction diagram
plt.plot(x, y)
plt.xlabel('2θ')
plt.ylabel('Intensity')
plt.title('X-ray Diffraction Diagram')
plt.show()

这段代码会读取名为drx-sample1.xy的文件，并将文件中的数据转换为numpy数组。然后，使用matplotlib库绘制出X射线衍射图，并在图表中显示2θ和强度。
