如何在 Anaconda 提示符下运行 .py 文件时将 matplotlib 图形标题包含在窗口中

Question

import numpy as np

 from matplotlib_venn import venn2, venn2_circles, venn2_unweighted

 from matplotlib_venn import venn3, venn3_circles

 from matplotlib import pyplot as plt

 plt.title(print("Shared",Signature_1, 'and',Signature_2, 'and',Signature_3))

 venn3(subsets = (len(NameA), len(NameB), len(shared_A_B), len(NameC), len(shared_A_C), 

 len(shared_C_B), len(shared_A_B_C)), set_labels = (Signature_1, Signature_2, Signature_3), alpha = 0.5)

 plt.show()

此代码仅生成 jupyter Notebook 中绘图的标题。当我在 Anaconda 提示符下运行 .py 脚本时，只有绘图可见。我该如何让标题出现在绘图窗口中？我意识到因为这些格式被格式化为采用变量 [plt.title(print("title",variable,etc.)] 他们不能在命令行中工作。任何建议将不胜感激

您可以使用该.format方法将变量包含到打印/标题中。import numpy as npimport matplotlib.pyplot as pltx = np.arange(0,10)y = x**2plt.plot(x,y)variable ='IamVar'Signature_1='one'Signature_2='two'Signature_3='three'# \n stands for newlineplt.suptitle("Moving title - {} and {},{} \n set=({},{})".format(Signature_1,Signature_2,Signature_3,len(x),len(y))                  ,size=8,x=0.3, y=0.6)plt.show()
