Print few lines in .pyx file

[rkoystart]

Hi, wanted to print few lines in doc.pyx files. So tried using the following print-statement

print("my required message", object)

and the above didnt work. Can anyone let me know how to provide a proper print statement and verify things.
And also have few doubts regarding .pyx, .pyi, .pyd files. Can anyone give me a breifing about what these files are actually used instead of .py files

All of those files are Cython. Depending on the context in Cython, print can work as it does in normal Python or pretty differently. Can you give an actual bit of sample code and the error?

Hi @polm , Thanks for the response.
I tried adding the following line in the contructor(init()) of the file doc.pyx in the path env/lib/python3.8/site-packages/spacy/tokens/doc.pyx
print("This is the contructor of the class doc")

and when i executed the following code in the terminal

import spacy
model = spacy.load("en_core_web_md")
doc = model("hello how are you")

I didnt get any print message i had added previously.

Cython needs to be compiled before you can use it. Take a look at the section on building spaCy, and note that after changes to Cython files you have to run python setup.py build_ext --inplace.

If it's your first time working with Cython it might help to go through a Cython tutorial first.
