Python create list and add element method to list

Today's learning content is related to the list in Python.

I. Create a list

1. Create a normal list

>>> Tabulation1 = [' The Holy Man ', ' canopy ', ' roll the curtain ']>>> tabulation1[' st ', ' canopy ', ' roller blinds ']

>>> Tabulation2 = [72,36,18]>>> tabulation2[72, 36, 18]

2. Create a mixed list

>>> Mix tabulation = [' The Holy Man ', 72, ' canopy ', 36]syntaxerror:invalid syntax>>> mixtabulation = [' The sage ', 72, ' canopy ', 36 ]>>> mixtabulation[' Holy Sage ', 72, ' canopy ', 36]

3. Create an empty list

>>> empty = []>>> empty[]

There are three ways to introduce you, and next, what do you do if you want to add elements to the list?

Two. Adding elements to the list

1.append

>>> tabulation1.append (' Purple Chardonnay ')
>>> Tabulation1
[' The Holy Man ', ' canopy ', ' roller blinds ', ' violet Chardonnay ']

2.extend

>>> tabulation1.extend ([' Purple Chardonnay ', ' Green Xia '])
>>> Tabulation1
[' The Holy Man ', ' canopy ', ' roller blinds ', ' Purple Chardonnay ', ' Purple Chardonnay ', ' Green Xia ']

There is a way to expand the list with extend, and it is important to note that this method uses a list to expand the list instead of adding elements directly, so add "[]" to "()".

3.insert

>>> Tabulation1.insert (1, ' Purple Chardonnay ') >>> tabulation1[' Holy sage ', ' Purple Chardonnay ', ' canopy ', ' roller blinds ', ' Purple Chardonnay ', ' Purple Chardonnay ', ' green Chardonnay '

Do not want to eat in situ and so die, so I choose to progress a little bit every day.
