A first use of python function
python
Solution
you are importing a module, not the function. If you want to import just the function you could do this:
from prthis import prthis
g,t = prthis(7)
but if you import the full module you have to define the module you are calling the function from as well:
import prthis
g,t = prthis.prthis(7)
Problem
Sorry for the very silly question. I am a self-study beginner in python and I am having issues with using a function and calling it. I am coming from a MATLAB background so i was trying to do something similar. Tools used: Python 2 in a Linux environment As a test, I created a function that i called prthis (for "print this") within a file called also prthis.py. This function just takes a number as an input, and then outputs two numbers, respectively the same one and its square. I defined it like this: ``` #---------------------------------------- # content of the file prthis.py #---------------------------------------- def prthis(x): y=x*x nb=x return (y, nb) #------------------------------------------ ``` then, within the python prompt, I try to call the newly created prthis function, and I do this: ``` >>> import prthis >>> g,t = prthis(7) ``` The import seems to be succesful, but when I try the function on two outputs variable called g and t , like above, i get the following error message: ``` Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: 'module' object is not callable ``` Perhaps I am too much MATLAB-izing my thinking. Does anyone has a suggestion on how to deal with this? PS: it's my first question ever on stackexchange, so please could you let me know how to thank/accept valuable answers from other users? I do not wish to look like ungrateful to those who would try to help.
