Pythonrange()function generates theimmutable sequence of numbersstarting from the given start integer to the stop integer. Therange()is a built-in function that returns a range object that consists series of in
所以说,在python3.x版本中range(1,3) == [1,2],会返回False。而在2.x版本中则会返回True。因为在python3.x中,range()有了自己的类型,所以造成了结果的不同。这样的后果就是,python3.x中,你不能使用切片来访问range()的返回值了。幸运的是,你可以通过list()函数将range类型转换成一个列表来使用。 但...

factorial(n) for n in range(terms)) Here, you also apply a decorator to a function that has already been defined. In line 4, you decorate factorial() from the math standard library. You can’t use the pie syntax, but you can still manually apply the decorator. The approximation of e...
