Python array conditional filtering filter function Use example

Use the filter function to implement a conditional judgment function.

For example, to filter out a sensitive word in a string array, the sample code is as follows:

#filter out some unwanted tags def passed (item): Try:return Item! = "Techbrood" #can be more a complicated condition here Except Valueerror:return False org_words = [[' This ', ' Is '],[' demo ', ' From '],[' Techbrood ']] words = [Filter (passed, item) F or item in Org_words]

Note that python2.x and python3.x are not compatible with Filter/map, and return a list directly inside the python2.x.

Returns a Iterable object in the python3.x, for example , the following string is the object reference address.

You can use the list (words) transformation.
