函数(测试环境:ipython)
-
abs(x). Return the absolute value of a number. -
all(iterable). Return True if any element of the iterable is true. If the iterable is empty, return False.
hasattr(myObj, '__iter__')
#或者
In [19]: a=[]
...: a.__iter__
...: a.__iter__()
...:
Out[19]: <list_iterator at 0x7fac201854e0>
-
any(iterable). ReturnTrueif any element of the iterable is true. If the iterable is empty, returnFalse. -
ascii(object). Asrepr(), return a string containing a printable representation of an object
In [8]: ascii([1,2,3,4])
Out[8]: '[1, 2, 3, 4]'
In [9]: a=ascii([1,2,3,4])
In [10]: type(a)
Out[10]: str
-
bin(x). Convert an integer number to a binary string prefixed with “0b”.
In [18]: bin(123)
Out[18]: '0b1111011'
