py:run

py:run python-statement

Runs the given Python statements in the current Python session. To make multi-line Python code easier to run, this command will take multiple strings, each of which will be interpreted as a separate line of Python code. For instance:

(py:run
  "import matplotlib"
  "matplotlib.use('TkAgg')"
  "import numpy as np"
  "import matplotlib.pyplot as plt"
  "for i in range(10):"
  "    plt.plot([ x ** i for x in np.arange(-1, 1, 0.1) ])"
  "plt.show()"
)

py:run will wait for the statements to finish running before continuing. Thus, if you have long running Python code, NetLogo will pause while it runs.
