A step-by-step guide on how to check if a NumPy array is multidimensional or one-dimensional in multiple ways.
import pandas as pd import numpy as np df = pd.DataFrame({"A": [1, np.nan, 2], "B": [5, 6, 0]}) Which would look like: >>> df A B 0 1.0 5 1 NaN 6 2 2.0 0 First option I know one way to check if a particular value is NaN: >>> df.isnull(...
Python NumPy maximum() or max() function is used to get the maximum value (greatest value) of a given array, or compare the two arrays element-wise and return the maximum values. While comparing, one of the elements of two arrays is a NaN, then that element is returned as NaN. If ...
>>> import numpy as np >>> any([~np.isnan(np.float_(x)) for x in [np.nan, np.NaN, None, 'NaN', 'nan']]) False Pandas has a notna function that works for None and various NaNs (but not NaN as a string). >>> import pandas as pd >>> any([pd.notna(x) for x...
Lastly, using boolean indexing, We can filter all the nonnanvalues from the original NumPy array. All the indexes withTrueas their value will be used to filter the NumPy array. To learn more about these functions in-depth, refer to theirofficial documentationandhere, respectively. ...
