How to use Python single-line code to achieve specific functions

This article will explain in detail how to use Python single-line code to achieve specific functions. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

1) multiply each element in the list by 2

Code: print map (lambda XRO XJZ 2 Magi range (1m 11))

2) find the sum of all the elements in the list

Code: print sun (range (1meme 1001))

3) query whether a character creation contains a specific word

Code: wordlist= ["scala", "akka", "play framework", "typesafe"]

Tweet= "this is an example tweet talking about scala and sbt"

Print map (lambda x in tweet.split (), woordlist)

4) read the file

Code: print open ("ten_one_liners.py"). Redlines ()

5) print the song "Happy Birthday to you" in one sentence

Code: print map (lambda x: "Happy Birthday to" + ("you" if xeroids 2 else "dear Name"), ragne (4))

6) filter the values in the list

Code: print reduce (lambda (aforme b), c: (a + [c], b) if c > 60 else (arecine b + [c]), [49Perry 5876mine82jorn90], ([], [])

7) obtain XML webservice data and analyze

From xml.dom.minidom import parse,parseString

Iprort urllib2

# Note, convert it to XML format and print it out

Print parse (urllib2.urlopen ("http://search.twitter.com/search.atom?&q=python")).toprettxml(encoding="utf-8")

8) find the smallest or largest number in the list

Print min ([14, 35, 14, 35, 7, 46, 98)

Print max ([14, 35, 14, 35, 7, 46, 98)

9) parallel processing

Imprty multiprocessing

Import math

Print list (multiprosessing.Pool (processes=4) .map (math.exp,range (1m 11)
