Theitertoolsmodule in python is used to iterate over the given data structures. Use chain() in itertools module to join the given iterables. It takes all iterable you would like to join as an argument and returns an itertools.chain, you need to convert this to list using list(). 3.1.1...
__phone是私有属性,在外部是不可调用的,tom.__get_phone()报错“属性不存在”。 在类的内部对受保护对象和私有对象没有访问限制。_get_age可以调用私有属性__phone。 对应方法也是类似。 classPerson():name='name'# 共有属性 public_age=0# 受保护属性 protected__phone='phone'# 私有属性 privatedef__in...
元组tuple没有像list一样的append(),insert()方法,其他获取元素的方法和list是一样的,可以使用classmates[0],但不能赋值成另外的元素。因为tuple()不可变,所以代码也更安全。如果可能尽量使用tuple替代list。 python3 内置函数 () abs() 获取绝对值

For example, given the above output, if you want to use the microphone called “front,” which has index 3 in the list, you would create a microphone instance like this: Python >>> # This is just an example; do not run >>> mic = sr.Microphone(device_index=3) For most projects...
In Python 2, an implicit str type is ASCII. But in Python 3.x implicit str type is Unicode.xrangexrange() of Python 2.x doesn't exist in Python 3.x. In Python 2.x, range returns a list i.e. range(3) returns [0, 1, 2] while xrange returns a xrange object i. e., xrange...
