Innovation is not scary, scary is the user is very impatient animals. So, don't let them think, they're too lazy to think.Some developers will say, do not go, I will teach you how to use, I will do a good job of learning to guide the function.

Brief introduction: I recently wrote an FTP search engine on the internal network. due to the word segmentation of Chinese strings, I used a combination of forward and reverse, and I needed to reverse the Chinese strings. I searched for it online and read it almost all. they all needed loops. I didn't like it ve

dict () to DictionaryYou can use dict () to convert a sequence containing a dual-value subsequence into a dictionary.(You may often encounter this seed sequence, such as "strongren, 90, Carbon, 14" or "Vikings, 20, Packers, 7 .) The first element of each sub-sequence acts as the key, and the second element acts as the value.>>> Lol = [['A', 'B'], ['C', 'D'], ['E', 'F']>>> Dict (lol){'C': 'D', 'A': 'B', 'E'
