VS Code from start

[snippsat]

Look at some useful features.

Format code
Before i did mention to install:

pip install autopep8 yapf black

Take a look at format code with the new star Black.
So right click and Format Document,after have choose "python.formatting.provider": "black"
Here a image on how it work have a long line with dict,list and tuple,right side after format.

Mess up some code before and after format.
Messed up:

import random
import time

class Coin:
    def __init__(self ):
      self.sideup="Heads"

    def toss(self):
            if random.randrange( 2)== 0: 
              self.sideup =  "Heads"
            else:
              self.sideup= "Tails"

def toss_result(  ):
  my_coin=Coin( )
  print(f"This side is up: {my_coin.sideup}")
  print("I am tossing the coin...")
  time.sleep(4)
  my_coin.toss()
  print(f"This side is up: {my_coin.sideup}")

if __name__ == "__main__" :
  toss_result( )

After format:

import random
import time

class Coin:
    def __init__(self):
        self.sideup = "Heads"

    def toss(self):
        if random.randrange(2) == 0:
            self.sideup = "Heads"
        else:
            self.sideup = "Tails"

def toss_result():
    my_coin = Coin()
    print(f"This side is up: {my_coin.sideup}")
    print("I am tossing the coin...")
    time.sleep(4)
    my_coin.toss()
    print(f"This side is up: {my_coin.sideup}")

if __name__ == "__main__":
    toss_result()

IntelliSense
One of the strong feature with editor is IntelliSense
It goes beyond auto completion.
You can view available methods, parameter hints, short documentation, source code(where is function/method source code) etc...
If take mouse over get() method:

Need to scroll method doc or that it stay open ctrl+space.
Now can also look at source code for this get() function alt+f12(peek).
F12 goes to source code where get() is defined.

Linter
You annoying friend pylint

pip install pylint flake8

So i turn it of in normal use,then just turn it on if want a check of code.
Command Palette ctrl+shift+p search Pylint then get an option on/off.
So how dos it work:

What it finds is down in left corner errors and Warnings .
Click on it and it show up in windows under.
So the fix is pretty obvious missing {.

print(f"This side is up: {my_coin.sideup}") 

Save and this error/advise goes away.
