Python创建了一个X元素列表，其中的元素按Y计数。例如，如果X = 4且Y = 5，您将收到[5、10、15、20]

Question

This is what I have tried so far:

x = 4
y = 5
z = []
for i in range(x):
    i=i*y
    z.append(i)

But my output is showing: [0, 5, 10, 15]

How do I get indexing to start on 5 and go to 20?

Answer 1

So the problem you are having is the range of numbers you are generating:

>>> x = 4
>>> list(range(x))
[0, 1, 2, 3]

Just change

range(1, x + 1)

And see the documentation for range .

Answer 2

仅使用range方法即可生成列表。

z = list(range(y, x*y + 1, y))

Answer 3

You can add one to i

x = 4
y = 5
z = []
for i in range(x):
    i=(i+1)*y
    z.append(i)

Answer 4

You can use a list comprehension as well.

x = 4
y = 5
z = [y + i * y for i in range(x)]
