However, if, after running the above examples, you print out the original DataFrame with the codeprint(sales_data), you’ll find that the original dataframe (sales_data) is exactly the same. Unsorted. Syntactically, this is because theinplaceparameter is set toinplace = Falseby default. If...
Using the API with the served model This example was done using a pre-trained model (created by running igel init --target sick -type classification) and the Indian Diabetes dataset under examples/data. The headers of the columns in the original CSV are ‘preg’, ‘plas’, ‘pres’, ‘s...
Also, it takes values as a parameter which is a column name and its values will be the final values of the new columns of the new DataFrame. To work with pandas, we need to importpandaspackage first, below is the syntax: import pandas as pd ...
