问题 I am trying to run a game me and my friends made in python... It was sent to me by e-mail. i know i have a newer version of python but im not sure if that is the problem. This is the function we defined: def text(x,y,text,size): turtle.penup() turtle.goto(x,y) turtle.pendown() turtle.write(text,font=('Arial',size,'normal')) we call it here: def home_screen(): turtle.bgpic("bgarmy.gif") turtle.fillcolor("#46B347") turtle.fill(True) rectangle(-150,100,300,100) turtle.fill(False) text(-70,130,

问题 This is somewhat an extension of my previous question, but after solving that problem I am getting a different AttributeError . This one reads '_RatingsDescriptor' object has no attribute 'cumulative_score' when trying to do something like this in my view: def index(request): thing_list = Thing.ratings.cumulative_score() return render(request, 'index.html', {'thing_list':thing_list}) My model: from ratings.models import Ratings class Thing(models.Model): user = models.ForeignKey(User) ...

问题 I use Sublime Text and have a problem with that code: #coding: utf-8 import turtle turtle.circle(20) answer = turtle.textinput("Title", "Text") When i run it, i get: AttributeError: 'module' object has no attribute 'textinput' How can i fix it? 回答1: You are using Python 2. Run import sys print(sys.version) and it will probably output something like 2.7.12 (v2.7.12:d33e0cf91556, Jun 26 2016, 12:10:39) [GCC 4.2.1 (Apple Inc. build 5666) (dot 3)] which means that you are using Python 2.

问题 I'm trying to run a speech recognition using the Speech Recognition Project I installed SpeechRecognition as illustrated. My code ran correctly for a few times. I was trying to input different files. Now I started getting the following error: import speech_recognition as sr Traceback (most recent call last): File "<ipython-input-1-a4d5c9aae5d0>", line 1, in <module> import speech_recognition as sr File "/Users/Sashank/Documents/Deep_Learning_A_Z/Personal Projects/Speech recognition/speech

问题 I have a set of python files which make up a program for saving tidbits of info and searching them via tag association. I had the program working for many versions, but I recently made what I thought was a minor change that caused the program to go haywire. The ENTRY object is the basis of the data storage - it holds a unique ID number, a nickname, a value, and a list of tags. class ENTRY: def __init__(self, idNum, nickName, value, tagList): self.idNum = idNum self.nickName = nickName self

问题 I have a bunch of data stored in vals . The indices are monotonic, but not continuous. I'm attempting to do some analysis on histograms of the data, so I've created the following structure: hist = pd.DataFrame(vals) hist['bins'] = pd.cut(vals, 100) This is data taken from an experimental instrument and I know that some of the bins have only 1 or 2 counts in them, which I'm trying to remove. I've tried using groupby as follows and get the following error (Full traceback included at the end of

问题 I'm trying this simple code: import requests print requests.__file__ r = requests.get('https://github.com/timeline.json') It works flawlessly on the command line when I type the lines one by one, but not whenen when I execute it as a script or in Sublime Text 2. Here's the stack trace: C:\Python27\lib\site-packages\requests\__init__.pyc Traceback (most recent call last): File "C:\Users\Bruce\Desktop\http.py", line 1, in <module> import requests File "C:\Python27\lib\site-packages\requests\_

问题 I am debugging python code (python2.7.12) as my code works but I get NULL for all variables when streaming tweets into the database. The error I got is: Exception AttributeError: "'NoneType' object has no attribute 'path'" in <function _remove at 0x10068f140> ignored I am assuming this error is from the code below: def put_tweets_in_database(tweets): print "putting tweets in database" errors = 0 count = 0 for tweet in tweets: try: commit_tweet_to_database(tweet, count, len(tweets)) count += 1

问题 I am trying to get a hold of SciPy, but I am stuck with Unknown property density error, even though I copied the whole code from official SciPy documentation. This part worked fine: x = np.linspace(norm.ppf(0.01), norm.ppf(0.99), 100) ax.plot(x, norm.pdf(x), 'r-', lw=5, alpha=0.6, label='norm pdf') rv = norm() ax.plot(x, rv.pdf(x), 'k-', lw=2, label='frozen pdf') r = norm.rvs(size=1000) But the following part gives me the AttributeError: Unknown property density : ax.hist(r, density=True,
