Debugging tactics can involve the following: ● Interactive bugging ● Control flow analysis ● Unit testing ● etc. 29 Debugging in Spyder Start Debugging Execute current line Stop Debugging Code Fix Press Ctrl + F5 to start debugging. Execute code line by line until Press Ctrl + Shift + F12 to stop Edit the part of the code where you noticed the bug, mistake, or debugging. the bug, mistake, or flaw is flaw. found. 30 Start debugging 31 Execute the current line of code 32 After line 15 execution, bug found 33 Stop debugging mode, bug fix 34 Re-execute the whole file, meet desired result 35 8 Plots View plotted charts plotted by matplotlib Sample matplotlib code execution 37 Plots viewing 38 9 Advanced Usage Preview of Spyder advanced usage Advanced Usage Since Spyder is an IDE for scientific programming, data-related programming and engineering is Data-related programming: ● Data analysis ● Data visualization ● Machine learning ● etc. 40 Dataset import 41 Dataset inspection 42 Dataset sorting 43 Dataset value formatting (viewing-only) 44 Value formatting 45 Prediction and plotting 46 Thanks!
