1、str.split()
spade :黑桃♠️；diamond:方块♦️；club：梅花♣️；heart：红桃♥️
>>> 'spades diamonds clubs hearts'.split()
['spades', 'diamonds', 'clubs', 'hearts']
>>> 'spades diamonds clubs hearts'.split(' ',1)
['spades', 'diamonds clubs hearts']
>>> 'spades diamonds clubs hearts'.split(' ',2)
['spades', 'diamonds', 'clubs hearts']
>>> 'spades diamonds clubs hearts'.split(' ',3)
['spades', 'diamonds', 'clubs', 'hearts']
2、list()
>>> list('JQKA')
['J', 'Q', 'K', 'A']
>>> atuple = (123,'234')
>>> list(atuple)
[123, '234']
>>> list((123,'234'))
[123, '234']
>>> list(123)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
3、list + list>>> >>> [str(n) for n in range(2,11)] + list('JQKA')
['2', '3', '4', '5', '6', '7', '8', '9', '10', 'J', 'Q', 'K', 'A']
4 、s[i:j:k] 含义从第i到第j，中间间隔 k
>>> s = range(20)
>>> w = s[::3]
>>> print(w)
range(0, 20, 3)
>>> for i in w:
... print(i)
...
