In that case, converting theNumPy arrays(ndarrays) toDataFramemakes our data analyses convenient. In this tutorial, we will take a closer look at some of the common approaches we can use to convert the NumPy array to Pandas DataFrame. We will also witness some common tricks to handle differe...
# Quick examples to convert numpy array to dataframe # Example 1: Convert 2-dimensional NumPy array array = np.array([['Spark', 20000, 1000], ['PySpark', 25000, 2300], ['Python', 22000, 12000]]) df = pd.DataFrame({'Course': array[:, 0], 'Fee': array[:, 1], 'Discount': ...
Use the.to_numpy()method for a direct and efficient conversion of a DataFrame to a NumPy array. You can convert specific columns of a DataFrame to a NumPy array by selecting them before applying.to_numpy(). The.to_records()method can be used to convert a DataFrame to a structured NumPy...
