我需要你的帮助!我有一个绘图代码如下:
fig = plt.figure()
ax1 = fig.add_subplot(111)
imax1 = ax1.imshow(data,interpolation = 'nearest', origin = 'lower',cmap=cm.jet)#plot
cbar = plt.colorbar(imax1, extend='neither', spacing='proportional',
orientation='vertical', shrink=0.7, format="%.0f")
cbar.set_label(r"ET [mm/month]", size=10)
titlestr = "Evapotranspiration in mm/month"
plt.title(titlestr)
#plt.xlabel("Longitude")
#plt.ylabel("Latitude")
imax1.set_clim(0,60)
labels = [item.get_text() for item in ax1.get_xticklabels()]
for ii in range(np.shape(labels)[0]):
labels[ii] = str(grid_lon[75*ii/np.shape(labels)[0]])
ax1.set_xticklabels(labels, rotation = 45, ha='right', size = 10)
labels = [item.get_text() for item in ax1.get_yticklabels()]
for ii in range(np.shape(labels)[0]):
labels[ii] = str(grid_lat[75*ii/np.shape(labels)[0]])
ax1.set_yticklabels(labels, size = 10)
pngname = "./out/2d_"+variable+"_"+mm+".png"
print "save …我有一个关于python的简单问题。ndarray我想选择整列，而不是遍历 3D 的第一行。所以让我们说：而不是：
print test[0][20][33]
print test[1][20][33]
...
我想放一些类似的东西：
print test[:][20][33]
但这不起作用。我该怎么做？
