finally:

# tick_params参数
# 参数axis 选择坐标轴,both/x/y
# 参数which的值为 'major'、'minor'、'both',分别代表设置主刻度线、副刻度线以及同时设置,默认值为'major'
# 参数direction的值为'in'、'out'、'inout',分别代表刻度线显示在绘图区内侧、外侧以及同时显示
# 参数labelsize用于设置刻度线标签的字体大小
# 参数bottom, top, left, right的值为布尔值,分别代表设置绘图区四个边框线上的的刻度线是否显示
# 参数labelbottom, labeltop, labelleft, labelright的值为布尔值,分别代表设置绘图区四个边框线上的刻度线标签是否显示
plt.tick_params(which='major', labelsize=16, colors="red", direction='in')
plt.show()
