[英]index out of bounds error: Python
In a code I was writing, I keep getting the index error "index out of bounds" however, I don't see a reasonable way that it would give me the error. 在我编写的代码中,我一直使索引错误“索引超出范围”,但是,我没有找到一种合理的方式来给我错误。
Here is where I get this error: 这是我收到此错误的地方:
def data_point(box_size):
np.random.seed(250)
x_data = np.random.uniform(-1, 1, 40)*box_size*0.5
y_data = np.random.uniform(-1, 1, 40)*box_size*0.5
for i in x_data:
print "(", x_data[i], ",", y_data[i], ")"
return x_data, y_data
This is a part of code that I am using. 这是我正在使用的代码的一部分。 Whenever I run this I get an error from the fifth line here.
每当我运行此命令时,我都会从第五行收到错误消息。 If I just simply put range(40) instead the error goes away.
如果我只是简单地将range(40)放进去,错误就会消失。 Any ideas?
有任何想法吗?
i
is not an index. i
不是指数。 i
is the data itself . i
就是数据本身 。 If you wanted to pair up the arrays, just use zip()
: 如果要配对数组,只需使用
zip()
:
for x, y in zip(x_data, y_data):
print "(", x, ",", y, ")"
For cases where you need an index, you can use the enumerate()
function to add an index: 对于需要索引的情况,可以使用
enumerate()
函数 添加索引:
for i, x in enumerate(x_data):
print "(", x, ",", y_data[i], ")"
or you can use range()
with len()
to produce a certain number of indices: 或者您可以将
range()
与len()
以产生一定数量的索引:
for i in range(len(x_data)):
