如何在Python中生成网格二维图形？

import matplotlib.pyplot as plt

# 定义网格的行数和列数
rows = 10
cols = 10

# 创建一个新的图形
fig, ax = plt.subplots()

# 绘制网格线
for i in range(rows+1):
    ax.axhline(y=i, color='gray', linestyle='-', linewidth=0.5)
for j in range(cols+1):
    ax.axvline(x=j, color='gray', linestyle='-', linewidth=0.5)

# 设置坐标轴范围
ax.set_xlim(0, cols)
ax.set_ylim(0, rows)

# 隐藏坐标轴刻度
ax.set_xticks([])
ax.set_yticks([])

# 显示图形
plt.show()
