Python Range

 >>> 

>>> [a for a in range(2,11,2) ]

[2, 4, 6, 8, 10]

>>> [a for a in range(2,11,2) if a>4]

[6, 8, 10]

>>> [a**2 for a in range(2,11,2) if a>4]

[36, 64, 100]

>>> 

filtering a list with other list

>>> l=[a for a in l if a not in ['Casa',0]]

>>> l

['Television', 10, 'Pistola']

 

>>> l=[a for a in l if a not in ['Casa',0]]

>>> l

['Television', 10, 'Pistola']

Switch Match

 >>> def http(e):

...    match e:

...       case 400:

...          print('Error 400')

...       case 401:

...          print('Auth request')

...       case _:

...          print('Unknow error')

... 

>>> http(12)

Unknow error

>>> http(500)

Unknow error

>>> http(400)

Error 400
