import ee
import geemap.core as geemap
print('First non-zero in [0, 5]:',
ee.Number(0).firstNonZero(ee.Number(5)).getInfo()) # 5
print('First non-zero in [5, 0]:',
ee.Number(5).firstNonZero(ee.Number(0)).getInfo()) # 5

It returns the `left` value if it's non-zero; otherwise, it returns the `right` value. The method is available in both JavaScript and Python, operating on numerical data. Examples show that `firstNonZero` selects 5 when given (0, 5) or (5, 0) as inputs.\n"]]
