Build-in Function:abs(),all(),any(),assii(),bin(),issubclass(),bytearray(),isinstance()

print('abs():输出绝对值,是absolute的缩写--------------') print(abs(-1)) print('all()与any()---------------------------') #all都为真时才为真,但是空的为真,any()有一个为真时就是真的 jo1_list=[1,2,3,4,5,6,7] jo2_list=['',2,3,4,5,7] jo4_list=[0,2,3,4,5,6,7] jo5_list=[False,2,3,4,5,6,7] j…

Python的内置方法，abs,all,any,basestring,bin,bool,bytearray,callable,chr,cmp,complex,divmod

Python的内置方法 abs(X):返回一个数的绝对值,X可以是一个整数,长整型,或者浮点数,如果X是一个复数,此方法返回此复数的绝对值(此复数与它的共轭复数的乘积的平方根) >>> abs(3+2j) 3.605551275463989 >>> abs(3-2j) 3.605551275463989 all(iterable):如果迭代器的所有元素都是true,或者空迭代器,则此方法返回true. any(iterable):迭代器只要有一个元素为false,或者空…
