Put robots.txt and sitemap.xml into your app’s static directory and define this view: from flask import Flask, request, send_from_directory @app.route(‘/robots.txt’) @app.route(‘/sitemap.xml’) def static_from_root(): return send_from_directory(app.static_folder, request.path[1:])
Creating an empty dataframe with the same index and columns as another dataframe: import pandas as pd df_copy = pd.DataFrame().reindex_like(df_original)
Another alternative: df[‘week_start’] = df[‘myday’].dt.to_period(‘W’).apply(lambda r: r.start_time) This will set ‘week_start’ to be the first Monday before the time in ‘myday’. You can choose different week starts via anchored offsets e.g. ’W-THU’ to start the week on Thursday instead. (Thanks @Henry Ecker for that suggestion)
Three suggestions: Use one dictionary. It’s easier, it’s more straightforward, and someone else has already optimized this problem for you. Until you’ve actually measured your code and traced a performance problem to this part of it, you have no reason not to do the simple, straightforward thing. Optimize later. If you are really worried about … Read more
You could solve this many ways. One that is pretty simple to understand is to just use a loop. def comp(list1, list2): for val in list1: if val in list2: return True return False A more compact way you can do it is to use map and reduce: reduce(lambda v1,v2: v1 or v2, map(lambda v: … Read more
You can setup a custom ModelChoiceField that will return whatever label you’d like. Place something like this within a fields.py or wherever applicable. class UserModelChoiceField(ModelChoiceField): def label_from_instance(self, obj): return obj.get_full_name() Then when creating your form, simply use that field UserModelChoiceField(queryset=User.objects.filter(is_staff=False), required = False) More info can be found here
In theory reflection in sqlalchemy should work for you. In this case I’m using an mssql database with two tables which have a simple Many-to-one relation: “Tests” with fields: id testname author_id (foreign key to the Users table, Users.id field) “Users” with fields: id fullname So the following should reflect the database: from sqlalchemy import … Read more
I faced the same problem because I created a file named abc.py, remove that file in your project, your error will disappear.
I had the same problem and I solved it by specifying the video output resolution to exactly the same as input: cap = cv2.VideoCapture(‘vtest.avi’) … out = cv2.VideoWriter(‘output.avi’,fourcc, 20.0,(int(cap.get(3)),int(cap.get(4)))) Of course make sure you got ffmpeg installed and working.
strip_tags actually removes the tags from the input, which may not be what you want. To convert a string to a “safe string” with angle brackets, ampersands and quotes converted to the corresponding HTML entities, you can use the escape filter: from django.utils.html import escape message = escape(form.cleaned_data[‘message’])
