python-3.4

问题 I am currently working on a script that needs to write to a .docx file for presentation purposes. I use pandas to handle all my data calculations in the script. I am looking to write a pandas dataframe into a table at a bookmark in a word.docx file using PyWIN32. The dataframe consists of floats. The psuedo code is something like this. frame = DataFrame(np.arange(28).reshape((4,7)), columns=['Text1',...'Text7']) With pywin32 imported... wordApp = win32.gencache.EnsureDispatch('Word

问题 Python 3.4.2 I am learning asyncio and I use it to continously listen IPC bus, while gbulb listens to the dbus. Some side notes: So I created a function listen_to_ipc_channel_layer that continously listens for incoming messages on the IPC channel and passes the message to a message_handler . I am also listening to SIGTERM and SIGINT. So when I send a SIGTERM to the python process running the code you find at the bottom, the script should terminate gracefully. The problem … I am having is the

问题 In python2.7 , I can analyze an hdf5 files keys use $ python >>> import h5py >>> f = h5py.File('example.h5', 'r') >>> f.keys() [u'some_key'] However, in python3.4 , I get something different: $ python3 -q >>> import h5py >>> f = h5py.File('example.h5', 'r') >>> f.keys() KeysViewWithLock(<HDF5 file "example.h5" (mode r)>) What is KeysViewWithLock , and how can I examine my HDF5 keys in Python3? 回答1: From h5py's website (http://docs.h5py.org/en/latest/high/group.html#dict-interface-and-links):

问题 So I wrote a for loop like this: for i in range(size): if(.....) .... i-=1 else: .... I try to decrease the index by 1 if it is inside the if statement, but apparently I can't do that. Is there any other way that I can decrease i in a for loop? 回答1: I would like to go over the range() function yet again through the documentation as provided here: Python 3.4.1 Documentation for range(start, stop[, step]) As shown in the documentation above, you may enter three parameters for the range function

问题 import pyautogui print (pyautogui.locateCenterOnScreen("C:\Users\Venkatesh_J\PycharmProjects\mouse_event\mouse_event.png")) Instead of returning coordinates, it returns None . 回答1: Seems like it couldn't find anything matching your image on the screen. locateCenterOnScreen(image, grayscale=False) - Returns (x, y) coordinates of the center of the first found instance of the image on the screen.

问题 I'm writing a program to help the school's Biology Department and it involves sending an email. I've gathered all of the variables I need for the content of the message, it's just the actual sending of the email that's causing some issues. I've looked around and realized that I was using code that sent to gmail, whereas the servers at school use Outlook 2010. Once I remembered that, I looked around for some python code that sent emails, but so far nothing has worked. It all seems very

问题 I am writing a script to read a csv file. The csv file and script lies in the same directory. But when I tried to open the file it gives me FileNotFoundError: [Errno 2] No such file or directory: 'zipcodes.csv' . The code I used to read the file is with open('zipcodes.csv', 'r') as zipcode_file: reader = csv.DictReader(zipcode_file) If I give the full path to the file, it will work. Why open() requires full path of the file ? 回答1: From the documentation: open(file, mode='r', buffering=-1,

问题 I'm running multiple installs of Python on Windows Server 2012. I can probably find a way to work around this, but I'm curious as to what is going on. I'm wary about radically changing the installs in case I break other people's Python scheduled tasks that I may not be aware of. (All the code boxes below are PowerShell). PS C:\> C:\Python34\Scripts\pip.exe list jdcal (1.0) pip (7.1.2) setuptools (12.0.5) virtualenv (13.1.2) Although this Python 3.4 install doesn't have Django installed, it

问题 I have successfully created a central python logging server on one computer and can log to it from multiple RPis. However when the logging server goes down the logs are lost. Is there a way to store the logs (in a persistent form) until the logging server becomes available again? I have looked at a few programs such as graylog, sentry and logstash but couldn't see any option to do this. Any help would be much appreciated. 回答1: I've come up with a custom socket handler, which buffers unsent

问题 I have both Python 2.7 and 3.4 on my Windows machine. I have pip, pip2, and pip3. Pip2 is 2.7 while the others are 3.4 when running pip(,2,3) -V However, pip -V , pip2 -V and pip3 -V All show the same thing about pips location and all but pip2 show that it's for Python3.4. For all three the location they show for pip is C:\Python27\site-packages. Which is fine for pip2, but for pip3, and pip(if posssible, not 100% necessary), they should show the location as C:\Python34 instead. Not sure why
