How does python work?
I recently upgraded my Prime to the latest firmware and I'm trying to understand how to write python functions/scripts. I didn't seem to find much a solution while perusing older threads.
Let's say my script looks like this: PHP Code: def func1(a, b): I know this is a contrived example, but I just want to know how to make it work. The question is, how do I call func3 ? |

RE: How does python work?
This will work
Code: def func1(a, b): return a + b def func2(a, b): return a - b def func3(a, b, c): if c == 0: return func1(a, b) else: return func2(a, b) d=func3(4,2,0) |

I am not looking to run the code from the python app. I am looking to run the code from the place where you do regular calculations. For example, if I was using python-syntax under XCas, I would do the following: PHP Code: #cas I'm looking to do the same but with python, not XCas. |

It just so happens that XCAS can accept some python syntax. What I am asking how to run python code, not XCAS with python-like syntax. |

RE: How does python work?
Maybe the PYTHON command is what you are looking for?
Code: #PYTHON test |

RE: How does python work?
I think you would have to save it as a variable, then do what ever you want with the variable like in the following example:
PHP Code: #PYTHON test You can also save it as a home variable with hpprime.eval instead of cas.caseval. -road |

RE: How does python work?
I don't know of any resources. There may be a better way to do what you want but that's the best I could come up with. Everything I know about Python on the prime was learned by trial and error (mostly error), and by reading posts in this forum.
