is the custom of naming in Python? I found that if the variable name was completely expanded, it would be too long-my MacBook Pro was too ugly to show up. This is followed by the variable shorthand naming of C + +.V. Entrance Call functionThe main function, similar to C + +. As soon as you run the knn.py script, the code is executed first:if __name__ = = ' __main__ ': print "You are running knn.py " CLASSIFYSAMPLEFILEBYKNN (' datingSetOne.txt '

Fortunately IntelliJ idea will be in the future for a long time, continuous updating. Give people more confidence. Although Eclipse is frequently updated, but in stability, subject to its cross-platform above all ideas, after many years of renewal, still no fundamental solution. Whether it can continue to attract people depends on its direction. Person
