问题 I'm trying to produce the average of numbers in a specified column in a text file. I am receiving an error that python could not convert string to float, although I don't see where I could be passing it an invalid string. def avg_col(f, col, delim=None, nhr=0): """ file, int, str, int -> float Produces average of data stored in column col of file f Requires: file has nhr header rows of data; data is separated by delim >>> test_file = StringIO('0.0, 3.5, 2.0, 5.8, 2.1') >>> avg_col(test_file,

问题 Does anyone know if it is possible to open a ljpg (lossless jpeg) file in Python? (specifically I'm using spyder on Windows XP). I've searched around on Google, here and the Python documentation and I can't see anything. If it's not possible, I'll try to work out how to call Octave to convert it, but it would be great if I didn't have to do that. Thanks! 回答1: Since the below didn't work, try this wrapper: http://ebiznisz.hu/python-jpegtran/ Appears to do the trick. http://www.pyglet.org/doc

问题 I run a pyqt4 application in spyder , I exit with QtGui.QMainWindow.close() and it returns me to the spyder python interpreter prompt. However, if I try and run the application again runfile('C:/Python33/~/qtapp.py', wdir=r'C:/Python33/~/Appdir') The window doesn't show. I have to shut the python interpreter window down and open a new one up before I can run my pyqt4 app again. This suggest to me that I am. Not shutting down the app correctly Not running the app correctly I want to be able to

问题 It looks like spyder IDE is pretty limited when it comes to debugging any scipy ML code as it is not possible to run scipy optimization methods or plotting libraries in debug mode. The kernel keeps on restarting . I am not sure how to debug my code particularly the scipy.optimize.minimize method( i don't want to go inside the method to debug but just want to execute it in a loop of 10 and read the parameter theta). I can do it easily in Octave. I am surprised that spyder python IDE lacks

问题 I've just changed from MATLAB to Python and I'm rather disappointed. I've installed Spyder 2.3 for Python 2.7 via terminal on my early '15 MBP (just for you to get an idea about the hardware) with OS X El Capitan installed on it and the IPython console it is pretty slow. Running simple commands like numpy's np.arange() or sometimes even while calculating fundamental things just as 1+1 , it takes between several seconds and a minute and sometimes it even freezes for a couple of minutes. Since

问题 I'm new to python and the virtual environment stuff. I'm facing issues opening jupyter notebook and Spyder after updating conda. Here are some info about the versions I have: $ conda info active environment : None '''is it caused by this ?

问题 I have a couple libraries that run fine in Spyder but not in PyCharm. import seaborn as sns import matplotlib.pyplot as plt In PyCharm, I thought I could click File > Settings and point the Project Interpreter to Python 3.6, which is what I'm using for Spyder, and that works fine. Is there some other setting that needs to be re-pointed? Or, is there something else that I'm missing? Finally, if I ned a new library, I go to the 'Anaconda Prompt' and 'pip install ...' the necessary library. Will

问题 Previously, I have been running Python in Spyder . I always started Spyder by directly double clicking its icon. Today, I suddenly realize that I have another thing called Python(x,y) . I notice that I can also start Spyder through it. Do these two methods make any difference? If not, what is the meaning of Python(x,y) ? Does it have any other good features? 回答1: Python(x,y) Python(x,y) is a scientific Python distribution . This means that it not only installs Python in your system but also
