How to search help using python console

Question

Is there any way to search for a particular package/function using keywords in the Python console?

For example, I may want to search \"pdf\" for pdf related tasks.

Answer 1

1. help(name of the function)
2. if you are using jupyter or ipython notebook ,then adding "?" would bring dogstring for the code. this is helpful if you want to see help of specific function.example pandas.read_csv?.
3. by pressing "Tab" you can see what you need to enter as parameters, although it would not give what a function does, but provide way to enter the input parameters.
