numpy Filtering data Directly filtering indices
Example
For simple cases, you can filter data directly.
a = np.random.normal(size=10)
print(a)
#[-1.19423121 1.10481873 0.26332982 -0.53300387 -0.04809928 1.77107775
# 1.16741359 0.17699948 -0.06342169 -1.74213078]
b = a[a>0]
print(b)
#[ 1.10481873 0.26332982 1.77107775 1.16741359 0.17699948]
