Newbie question: .isnan

[hshivaraj]

Here's another trick you may want to try

import math
from itertools import filterfalse

raw_data = [56.2, float('NaN'), 51.7, 55.3, 52.5, float('NaN'), 47.8]

filtered_data = list(filterfalse(math.isnan, raw_data))
print(filtered_data)

filtered_data = list(filter(lambda x: not math.isnan(x), raw_data))
print(filtered_data)

Output:
[56.2, 51.7, 55.3, 52.5, 47.8]
[56.2, 51.7, 55.3, 52.5, 47.8]
