1、数组运算多维数据：a=array([[ 1, 2], [ 3, 4]])b=array([[ 2, 2], [ 2, 2]])c=np.vstack((a,b)) #垂直d=np.hstack((a,b)) #水平e=a.tolist() #数组转列表f=np.array(e) #列表转数据2、画布画图https://j...

由于脚本中输出文件，如果一直调试这段代码，则每次都需删除文件，所以import osif(os.path.exists("abc_xz2.dat")): os.remove("abc_xz2.dat") print "remove abc_xz2.dat"else: print "abc_xz2.dat not exist"...

近期需要画contour图，好像也叫热图。注意x,y需要网格化，x.reshape(n,n); y=reshape(n,n)或者 (x,y)= meshgrid(x,y)一、无等高线plt.imshow(f(x,y),cmap=jet); #f(x,y)需要时方阵二、有等高线plt.contour(x,y,f(x,y),cmap=jet); #画等高线、轮廓图plt.cont...

已知x0=[1,2,3,4,5] y0=[1,2,3,4,5]若要把x0,y0输出到文件123.dat中，程序如下：法一：with open('123.dat','w') as f: for i,j in zip(x0,y0): f.write(str(i)) #将数值转换为字符串 f.write(" ...
