How many times have you been stuck in a situation where you have to change someone else's code? If you're part of a development team, you're more than you want to be in this situation. However, Python has a neat debugging feature (like most other languages), which is handy in this case. This is a quick tutorial and hopefully it will make your coding life easier.1.

to the specified number of rows If the current row is 10, note: If j 20 is executed, it is equivalent that the program directly jumps to 20 rows, with 11 ~ In fact, the 19 rows are directly skipped and are not executed at all. Therefore, if the variable declaration or object initialization in this code needs to be used in 20 rows or later, when used, an error may be reported!
