Question

python中列表全部赋0

python中能不能像C那样，比如我新建一个列表，并赋100个初值为0

Answer 1

>>> list=[0]
>>> list=list*100
>>> list
[0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0]
>>> len(list)
100

Answer 2

标准写法：
listVal = [];
for i in range(100):
listVal.append(0);

快速写法1：
listVal = [[0]*100];

快速写法2：
listZero = [0]
listVal = listZero * 100;

Answer 3

PythonList = [0] * 100就可以啦
