"debugger." A debugger is like doing a full-body scan on a sick person. YouDon't get any specific useful information, and you find a whole lot of information thatDoesn ' t help and is just confusing.2. The best-of-the-to-debug a program is-use print-to-print out the values of variables atPoints in the program to see where they go wrong.3. Make sure parts of the your programs work as your work on them. Do not write massive filesof code before you try

return function, try writing a few functions yourself to get them to return some values. You can put anything that can be placed on the right side as the return value of a function. The end of the script is a puzzle. I use the return value of a function as a parameter to another function. I link them together, just like I write math equations. It may be a bit hard to read, but you'll know the result if you run it. Next, you need to try to make t

knowledge help you with your list operations? Very simply, every time you say "I want a 3rd animal" to yourself, you need to convert the "ordinal" to "base", as long as the former minus 1 is OK. The index of the 3rd animal is 2, which is penguin. Since you've been dealing with ordinals all your life, you need to get the cardinality in this way, as long as you've lost 1.Remember: ordinal = = ordered, starting at 1; cardinal = = Randomly selected, star

Exercise 1: First programYou should spend a lot of time in Exercise 0, learn how to install a text editor, run a text editor, and run a command-line terminal, and you've taken the time to familiarize yourself with the tools. Please do not skip the contents of the previous exercise to do the following directly, this is the only one such warning of this book.1 Print "Hello world!"2 3 Print "Hello Again"4 5 Print "I like typing this."6 7 Print "This was

explain the meaning of the code to yourself through annotations. Explain how each function is used, the purpose of each variable, and any other aspect of the content, as long as it helps you to understand the code.Finally, each part of the code that is difficult to track, line-by-row or function-by-bit tracking variable values.

find a problem with the map, adjust the map so that the code and the map match each other.One last suggestion: Every programmer will be influenced by irrational fears when they start a big new project. In order to avoid this fear, they will stall time and end up doing nothing. I sometimes do that, everyone has this experience, the best way to avoid this situation is to make a list of what you want to do, o
