This also needs to be done as first step, in case we want to remove rows with inf values from a data set (more on that in Example 2). Have a look at the Python code and its output below: data_new1=data.copy()# Create duplicate of datadata_new1.replace([np.inf,- np.inf],np...
testdrop_20241015(name) values('ddcw'); insert into db2.testdrop_20241015(name) select name from db2.testdrop_20241015; insert into db2.testdrop_20241015(name) select name from db2.testdrop_20241015; insert into db2.testdrop_20241015(name) select name from db2.testdrop_20241015; insert into...
By usingdf.replace()function is used to replace infinite values with NaN, and then use thepandas.DataFrame.dropna()method toremove the rows with NaN, Null/None values. This eventually drops infinite values from pandas DataFrame. Theinplace=Trueparameter modifies the original DataFrame in place. ...
