Python Reading

• Browse Getting Started with SciPy

Key Ideas

• Trying a program that uses SciPy. (Note: ensure that numpy, scipy and matplotlib are installed)
• Running a program from the command line.

Installing NumPy, SciPy and MatPlotLib

• Mac:
  • pip3 install --user numpy
  • pip3 install --user scipy
  • pip3 install --user matplotlib
• Windows:
  • Download numpy
  • In the command prompt, from the director where numpy is downloaded: python -m pip install numpy-1.12.1+mkl-cp36-cp36m-win32.whl
  • Download scipy
  • In the command prompt, from the directory where scipy is downloaded: python -m pip install scipy-0.19.0-cp36-cp36m-win32.whl
  • Download matplotlib
  • In the command prompt, from the directory where matplotlib is downloaded: python -m pip install matplotlib-2.0.0-cp36-cp36m-win32.whl

In-Class Activity

• Download bessel.py

Active Learning

1. Run bessel.py from within IDLE and also via the command line.
2. Try some different arguments.
3. What are the two items that this code plots?
4. Do you understand the code? (Use SciPy documentation as needed.)
