Python Array conditional filter filter function using sample _python

Source: Internet
Author: User

Using the filter function, a conditional judgment function can be implemented.

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

#filter out some unwanted tags 
def passed (item): 
Try: Return 
item!= "Techbrood" #can to more a complicated co Ndition here 
except ValueError: Return 
False 

org_words = [[' This ', ' Is '],[' demo ', ' From '],[' Techbrood ']] 
words = [Filter (passed, item) for item in Org_words]

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

Returns a Iterable object in the python3.x, such as <filter object at 0x000000000251c978>, and the following number is the object reference address.

You can use the list (words) conversion.
