iter(object[, sentinel]):返回一个迭代对象,对象需要支持__iter__() 、__getitem__() 、__next__() 。 len(s):返回一个对象的长度。 list([iterable]):返回一个可变数组类型。 locals():它们提供了基于字典的访问局部变量的方式。 map(function, iterable, ...):将函数对象依次作用于表的每一个元素。
python基础2-内置函数built-in function #abs()取绝对值print(abs(-1))#all()如果一个可迭代对象里的所有元素都为真,返回True,print(all([0,1,-1]))#非0就为真#any()如果一个可迭代对象里的任何一个元素为真,就返回True,print(any([]))#ascii() 与repr()一样,把一个对象变成一个可打印的字符串...
