Intro to VSCode

Intro to VSCode

So to start off, I followed the VSCode python tutorial here

It touches on topics like how to use VSCode (properly), setting up virtual environments, using the debugging tool and more.

Useful general shortcuts

ctrl+shift+p : command palette
ctrl+k then ctrl+o : open folder
ctrl+o : open file
ctrl+shift+n : opens a new window
ctrl+shift+left/right_arrow_key : select the word ctrl+shift+alt+up/down_arrow_key : multiple line edits

Setting up virtual environment

open command palette
python create new environment
select .venv

Debugging

using the debugging tool:

(From left to right:
continue/pause, stepover, step into, step out, restart and stop)

Useful debugging shortcuts:

F9 : breakpoint
F5 : continue
F6 : pause
F10 : step over
F11 : step into
Shift+F11 : step out

The side panel:

Variable: shows the variables in the current debugging scope, including value and types
Watch: tracks the value of specific expressions or variables you’re interested in throughout the debugging session
Call stack: shows the hierachy of function calls, indicating the path the program took to reach the current point
Loaded scripts: lists all the scripts that have been loaded into the current debugging session, useful for navigating to different parts of the code or library being used which you can use to track variable changes and see what functions/methods is called.

Writing some code to debug with

Below is python code I wrote to use to practice debugging

def euros(pound):
    pound = float(pound)*1.19
    euro = round(pound,2)
    return euro

value = input("enter the value in £:")
print(f"£{value} is equal to €{euros(value)}")

#code that converts pound to euros

Personally I really like the step into, and step out functionality, because it lets you see the process that happens internally when you’re calling that func/method.

(but why no step back… )

And thats about it for today
