How can we call the documentation for NumPy and SciPy?
If you are unsure of how to use a particular function or variable in NumPy and SciPy, you can call for the documentation with the help of ‘?’. In Jupyter notebook and IPython shell we can call up the documentation as follows −
Example
If you want to know NumPy sin () function, you can use the below code −
import numpy as np np.sin?
Output
We will get the details about sin() function something like as follows −
We can also view the source with the help of double question mark (??) as follows −
import numpy as np np.sin??
Similarly, if you want to see the documentation and source of a particular SciPy function, you can use single question mark (?) and double question mark (??). Let’s have a look at the example below −
Example
from scipy import io as scio scio.loadmat?
Output
View the source of loadmat() function as follows
from scipy import io as scio scio.loadmat??
