hi guys, i'm beginner of python, i trying use math.sqrt() to count distance.
print math.sqrt(float(data[0][0]) - float(k_cluster[0][0]**2) + float(data[0][1]) - float(k_cluster[0][1]**2)))
for example:
data[0] = 12.1
data[0][0] = 15.125
data[0][1] = 13.214
k_cluster[0][0] = 5.34
k_cluster[0][1] = 6.78
when i use code above it tell me math domain error, but if without math.sqrt() it work normally
do you know what the problem??
