- 數(shù)學(xué)運算
絕對值
>>> abs(-1)
1
最大值
>>> max([1,2,3])
3
最小值
>>> min([1,2,3])
1
求和
>>> sum([1, 2, 3, 4, 5])
15
四舍五入
>>> round(2.6)
3
長度
>>> len('abc')
3
生成1到9
>>> range(1,10)
range(1, 10)
生成1到9，間隔為2
>>> list(range(1, 10, 2))
[1, 3, 5, 7, 9]
反轉(zhuǎn)序列
>>> list(reversed([1, 2, 3, 4, 5, 6]))
[6, 5, 4, 3, 2, 1]
- 類型轉(zhuǎn)換
轉(zhuǎn)換為整數(shù)
>>> int('5')
5
轉(zhuǎn)換為浮點數(shù)
>>> float('5')
5.0
轉(zhuǎn)換為字符串
>>> str(5)
'5'
轉(zhuǎn)換列表為元組
>>> tuple([1, 2, 3])
(1, 2, 3)
轉(zhuǎn)換元組為列表
>>> list((1, 2, 3))
[1, 2, 3]
轉(zhuǎn)換數(shù)字為ASCI碼
>>> chr(5)
'\x05'
轉(zhuǎn)換ASCI碼為數(shù)字
>>> ord('A')
65
轉(zhuǎn)換為二進(jìn)制
>>> bin(1024)
'0b10000000000'
轉(zhuǎn)換為八進(jìn)制
>>> oct(1024)
'0o2000'
轉(zhuǎn)換為十六進(jìn)制
>>> hex(1024)
'0x400'
哈希值
>>> hash('Passw0rd')
4702269041947070808
