Is there a way to replace existing values with NaN
Is there a way to replace existing values with NaN If you are using Pandas you can use instance method replace on the objects of the DataFrames as referred here In 106 df replace N A np NaN Out 106 x y 0 10 12 1 50 11 2 18 NaN 3 32 13 4 47 15 5 20 NaN In the code above the first argument can be your arbitrary input which you want to change Share
NumPy Nanmean Get Mean Ignoring NAN Values Spark By Examples
Copy optional value boolean pass true to create a copy of x or false to replace the values inplace by default true nan optional value int or float Fill NaN values with this value NaN values will be substituted with 0 0 if no value is given posinf optional value int or float Fill positive infinity values with this Python NumPy Replace NaN with zero and fill positive infinity for . Here is a quick explanation of the above snippet of code import numpy as np First we are importing the numpy library to create an array The standard and accepted alias for numpy is np Next we create an array with nan values with the help of np nan np nan is used to indicate that there is a NaN value in the data This newly created array is stored in an object called arr Step 2 Set NaN values in the array to the mean using boolean indexing Use the numpy isnan function to check whether a value in the array is NaN or not If it is set it to the mean value use the numpy nanmean function to get the mean of a Numpy array with NaN values Let s replace all occurrences of NaN in the above array with
