[FIXED] Numpy "SyntaxError: invalid decimal literal"

Issue

So i'm trying to do some math on this vector in numpy but defining it just yields an error.

I tried defining the vector like this: vert = np.array([1.7, 0.7782, -0.4158，1.0]) and it errored like this:

vert = vert = np.array([1.7, 0.7782, -0.4158，1.0])
                                           ^
SyntaxError: invalid decimal literal

I tried removing the negative sign but it still had that error.

Solution

You've used U+65292 (Fullwidth Comma) at the end of the decimal instead the expected comma symbol. Python is parsing that symbol as a part of the number. Comapre the following two lines:

vert = vert = np.array([1.7, 0.7782, -0.4158，1.0])
vert = vert = np.array([1.7, 0.7782, -0.4158,1.0])
