# Python Quick Referenceをゆっくり参照してみた 02 シーケンス (リスト・タプル・文字列) の演算

##### リスト
>>> a = [1,2,3]
>>> 1 in a
True
>>> 10 in a
False
>>> 2 not in a
False
>>> 20 not in a
True
>>> b = [4,5,6]
>>> a + b
[1, 2, 3, 4, 5, 6]
>>> a * 3
[1, 2, 3, 1, 2, 3, 1, 2, 3]
>>> c  = a * 3
>>> c
[1, 2, 3, 1, 2, 3, 1, 2, 3]
>>> c[4:7]
[2, 3, 1]
>>> c[4:7:2]
[2, 1]
>>> len(c)
9
>>> min(c)
1
>>> max(c)
3
>>> reversed(c)
<listreverseiterator object at 0x6fbf0>
>>> [i for i in reversed(c)]
[3, 2, 1, 3, 2, 1, 3, 2, 1]
>>> sorted(c)
[1, 1, 1, 2, 2, 2, 3, 3, 3]
>>> c
[1, 2, 3, 1, 2, 3, 1, 2, 3]
##### 文字列
>>> str = 'abc'
>>> 'a' in str
True
>>> 'd' in str
False
>>> 'c' not in str
False
>>> str2 = 'def'
>>> str + str2
'abcdef'
>>> str3 = str *3
>>> str3
'abcabcabc'
>>> str3[4:7]
'bca'
>>> str3[4:7:2]
'ba'
>>> len(str3)
9
>>> min(str3)
'a'
>>> max(str3)
'c'
>>> reversed(str3)
<reversed object at 0x78d670>
>>> [i for i in reversed(str3)]
['c', 'b', 'a', 'c', 'b', 'a', 'c', 'b', 'a']
>>> "".join([i for i in reversed(str3)])
'cbacbacba'
>>> sorted(str3)
['a', 'a', 'a', 'b', 'b', 'b', 'c', 'c', 'c']
>>> "".join(sorted(str3))
'aaabbbccc'
>>> str3
'abcabcabc'
