There are lots of books about Linux, blogs. Most of them will be "rude" to plug a lot of commands to the reader, so much more. NET programmer to be deterred. They passed by without entering the door.So I envision a smoother way of learning, which is to introduce Linux backgrounds and motivations in plain language first when learning commands. Just as all the online games have to introduce the history of the game, and then introduce the game operation.

Created on: 2016-02-29Update: 02-29Python version: 2.7 %r is good for debugging because it shows the raw data of the variable, while the other symbols are used to show the output to the user; Print will not output line breaks If you add one after each line of print (comma). argv command-line arguments are strings, so it is necessary to convert int () to a number when the number is involved, raw_input () is also a string. Common ways to read and write files: close,read,readline,tru

) behind each line of print, right? In this case, print will not output new line breaks and end this line to the next line.You should see the result:Bonus points Exercise1. Surf the web to find out what features Python Raw_input implements.2. Can you find any other usage of it? Test the example you searched for online.3. Write a paragraph in a similar format and change the question to your own.4. In relation to escape sequences, think about why the last line ' 6\ ' 2 ' has a \ ' sequence inside.

the 18th lesson of the stupid way to learn Python This class will create a function that is similar to the definition function in the C language. The author adds an English comment that explains the function at the beginning of each function. For ease of understanding, I will directly explain some of the code involved in the knowledge point after the original code. The definition function is what the autho
