java fiasco python succeeds ranking


since 20 There was TIOBE Since the index ,Java and C No longer in the top two for the first time .C It's still number one , But now it's Python Occupy the second place .

Some people say ,Python The recent popularity is due to data mining 、 The vigorous development of artificial intelligence and numerical computation . But I have a different view , I Believe Python Its popularity is related to a variety of general needs .

in the past , Most programming is done by programmers , But now programming skills are needed everywhere to get the job done , And there is a lack of good programmers . therefore , We need some simple programming problems that non programmers can handle , Something easy to learn , Rapid development and simple and smooth deployment ,Python All of these needs are met .

not long ago , I've got a flat tire and sent to the factory for repair , The repairman and I were chatting , I said when I worked in the software industry , He smiled. , He began to talk about his current hobbies with enthusiasm : use Python Programming . From that moment on , I know it Python It's going to be everywhere .
