Recall, you have created dataframe.csv in step 1 of the previous recipe.In step 2, you use the pandas.read_json() function to create a DataFrame object from a valid JSON string. You pass the JSON string from the output of step 2 in the previous recipe as an argument to this function...
You can type or copy code into an input field. The job uses this code to perform the data transformation. You can provide a code snippet in either Python or Scala. The code should take one or moreDynamicFramesas input and returns a collection ofDynamicFrames. ...

Thenp.arange()function can also create arrays in descending order by using a negative step value. Example: python import numpy as np array = np.arange(10, 0, -1) print(array) Output: csharp [10 9 8 7 6 5 4 3 2 1] Explanation:This example generates an array that starts at 10 ...
In this step, we create an array that will be used to annotate the Seaborn heatmap. We call the flatten method on the “symbol” and “percentage” arrays to flatten a Python list of lists in one line. The zip function which returns aniteratorzips a list in Python ⁽³⁾. We ru...
