The method which is described inside theapply()method returns a series or DataFrame (NumPy array or even a list). Let us understand with the help of an example, Python program to demonstrate the use of pandas groupby() and apply() methods with arguments ...
First, let’s import Pandas and Numpy: import pandas as pd import numpy as np Obviously we’ll need Pandas to use the pd.get_dummies function. But we’ll use Numpy when we create our data, in order to include NA values. Create example dataframe Next, we need to create a dataset that...

You can use only pure Python libraries and the NumPy library to run UDFs based on the requirements of the Python sandbox. You cannot use other third-party libraries, such as pandas. However, you can use the NumPy and pandas libraries that are pre-installed in DataWorks to run non-UDFs....
There are three other important Python libraries (which are bundled with the Canopy and Anacondainstallations of Python) that come in quite handy and are used within this notebook: numpy for data analysis using arrays, pandas for data manipulation within dat...
