TabPy executing Python code, SCRIPT_REAL is being called with (string)

Question

First time using TabPy and have the connections successfully set up. Within the "Create Calculated Field" button in Tableau, I have tried

SCRIPT_REAL("
import numpy as np
import pandas as pd
")

which results in "SCRIPT_REAL is being called with (string), did you mean (string, ...)? Additionally, how do I refer to the dataset such as I did in Python to execute the following?

data = pd.read_csv("C:/Users/.../dataset.csv")
data.head()

plt.figure(figsize=(7,7))
plt.pie(data['stroke'].value_counts(sort = True),
        explode = (0.05, 0), 
        labels = data['stroke'].value_counts(sort = True).index,
        colors = ["blue","green"], 
        autopct = '%1.1f%%')
 
plt.title('Pie Chart')
plt.show()
