如何在matplotlib中对齐tick标签？

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 100)
y = np.sin(x)

plt.plot(x, y)

plt.xticks(np.arange(0, 10, 2))
plt.show()

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 100)
y = np.sin(x)

plt.plot(x, y)

labels = ['A', 'B', 'C', 'D', 'E']
plt.xticks(np.arange(0, 10, 2), labels)
plt.show()

import numpy as np
import matplotlib.pyplot as plt

x = np.linspace(0, 10, 100)
y = np.sin(x)

plt.plot(x, y)

ticks = np.arange(0, 10, 2)
labels = ['A', 'B', 'C', 'D', 'E']

plt.xticks(ticks)
plt.gca().set_xticklabels(labels)
plt.show()
