如何在numpy和常规python中查找函数

Question

I have seemed to forgot the command to look for functions in python and in numpy? Are there shortcuts that one can use to search for functions in numpy and python? I know help is used assuming you know the name of the function. Is the function lookfor?

Answer 1

I think you are looking for help() and/or dir() . Try:

import os

help(os)

and:

dir(str)

Answer 2

In [9]: import numpy as np

In [10]: dir(np)[-10:]
Out[10]:
['vectorize',
 'version',
 'void',
 'void0',
 'vsplit',
 'vstack',
 'where',
 'who',
 'zeros',
 'zeros_like']
