You could use the Text widget: from tkinter import * root = Tk() text = Text(root) text.pack() root.mainloop() Or with scrolling bars using ScrolledText: from tkinter import * from tkinter.scrolledtext import ScrolledText root = Tk() ScrolledText(root).pack() root.mainloop()
CreateModelMixin along with all other mixin classes (Eg. ListModelMixin, UpdateModelMixin etc) are defined in rest_framework/mixins.py file. These mixin classes provide all the basic CRUD operations on a model. You just need to define a serializer_class and queryset in your generic view to perform all these operations. DRF has separated out these common functionality in separate … Read more
This article gives some techniques for running Ruby code from Python which should also be applicable in the reverse direction (such as XML-RPC or pipes) as well as specific techniques for running Python code from Ruby. In particular rubypython or Ruby/Python look like they may do what you want.
This is how you can do it: from sklearn.feature_extraction import text from sklearn.feature_extraction.text import TfidfVectorizer my_stop_words = text.ENGLISH_STOP_WORDS.union([“book”]) vectorizer = TfidfVectorizer(ngram_range=(1,1), stop_words=my_stop_words) X = vectorizer.fit_transform([“this is an apple.”,”this is a book.”]) idf_values = dict(zip(vectorizer.get_feature_names(), vectorizer.idf_)) # printing the tfidf vectors print(X) # printing the vocabulary print(vectorizer.vocabulary_) In this example, I created the tfidf vectors for … Read more
You want to warn with a DeprecationWarning. Exactly how you call it doesn’t matter that much, but the stdlib has a standard pattern for deprecated modules, like this: # doc string, top-level comments, imports, __all__ = import warnings warnings.warn(“the spam module is deprecated”, DeprecationWarning, stacklevel=2) # normal module code See the 2.7 sets source for … Read more
Use loc: wanted_data.loc[:, ‘age’] = wanted_data.age.apply(lambda x: x + 1)
Here are my debugging notes. Still not sure which package is causing the problem, but this does seem to fix it. The error you get when you first run pipenv install with pipenv version 2020.8.13. Traceback (most recent call last): File “/usr/local/bin/pipenv”, line 8, in <module> sys.exit(cli()) File “/usr/local/lib/python3.6/site-packages/pipenv/vendor/click/core.py”, line 829, in __call__ return self.main(*args, … Read more
Remember that Python int values are of arbitrary size. How does that work? Well, in CPython,1 an int is represented by a PyLong_Object, which has an array of 4-byte chunks2, each holding 30 bits3 worth of the number. 0 takes no chunks at all. 1 – (1<<30)-1 takes 1 chunk. 1<<30 – (1<<60)-1 takes 2 … Read more
C++ doesn’t have reflection. As a result, it is impossible to offer a reference to a variable by its name. But as @NicolBolas points out, even if reflection was present, there would be more needed. Not only would it require huge language support (telling the called function what the variables were in the calling scope), … Read more
It is necessary to have both the model, and the data on the same device, either CPU or GPU, for the model to process data. Data on CPU and model on GPU, or vice-versa, will result in a Runtime error. You can set a variable device to cuda if it’s available, else it will be … Read more
