I am trying to find the mean of a list. I believe the negative number in the beginning of my list is somehow throwing me for a loop.
Please show me the proper way to find the mean of this simple list.

```
B = [−5,3,12,190,−10]

print(np.mean(B))

#OUTPUT:

File "<ipython-input-35-5b44dec66063>", line 1
    B = [−5,3,12,190,−10]
          ^
SyntaxError: invalid character in identifier

```
