i just want plot particular time steps variable data
define rain=((rainnc(t=17))-rainnc(t=9)))
how can do it in python
any idea


### What did you expect to happen?

i want data only some time steps 
how can i eleminate other timesteps

### Minimal Complete Verifiable Example

```python
import xarray as xr
import cartopy.crs as ccrs
from cartopy import feature as cf
import matplotlib.pyplot as plt
import numpy as np

#Opening and reading data
data=xr.open_dataset(""heavyrain3.nc"")
print(data)


lon=data.lon[:]
lat=data.lat[:]


#lev_2=data.lev_2[:]

rainnc=data.rainnc[17-9]
#time=data.time[0]







ax = plt.axes(projection=ccrs.PlateCarree())

rainnc.isel(time=16, lev_2=0).plot.pcolormesh(cmap='Purples',add_colorbar=False);


#ax.set_extent([west, east, south, north])
ax.coastlines()
ax.add_feature(cf.BORDERS)

plt.savefig(""rain31.jpg"")
plt.show()
```


### Relevant log output

```python
raise ValueError(
