Is there a way to init a list without using square bracket in Python?
Is there a way to init a list without using square bracket in Python?
For example, is there a function like list_cons so that:
x = list_cons(1, 2, 3, 4)
is equivalent to:
x = [1, 2, 3, 4]
In [1]: def list_cons(*args):
...: return list(args)
...:
In [2]: list_cons(1,2,3,4)
Out[2]: [1, 2, 3, 4]
使用列表构造函数并将它传递给一个元组。
x = list((1,2,3,4))
I don't think that would be a particularly useful function. Is typing brackets so hard? Perhaps we could give you a more useful answer if you explained why you want this.
Still, here's a fun thing you can do in Python 3:
>>> (*x,) = 1, 2, 3, 4, 5
>>> x
[1, 2, 3, 4, 5]
You can even omit the parenthesis -- *x, = 1, 2, 3, 4, 5 works too.
