python-2.7

问题 I have a new numpy version under /opt/lib/python2.7/site-packages , and a standard (system) version under /usr/lib/python2.7/dist-packages . I want to temporarily use the new numpy version so I add the following at the beginning of my script: In [1]: import sys In [2]: sys.path.insert(1,'/opt/numpy/lib/python2.7/site-packages') In [3]: sys.path Out[3]: ['', '/opt/numpy/lib/python2.7/site-packages', '/usr/local/bin', '/usr/lib/python2.7/dist-packages', '/usr/lib/python2.7', '/usr/lib/python2.7

问题 Trying for days but can't install PySide2 on python 2.7.15 while got no problem on python 3.7. On Qt for python(which is the project name for the module PySide2) website at is written explicitly that python 2.7 is supported so that should be no problem. I succeeded installing PySide2 on python 3 using: pip install PySide2 then i tried installing PySide2 on python 2 using: python -m pip install PySide2 which yelled error: ERROR: Could not find a version that satisfies the requirement PySide2

问题 I'm using Python 2.7, requests & BeautifulSoup to scrape approximately 50 Wikipedia pages. I've created a column in my dataframe that has partial URL's that relate to the name of each song (these have been verified previously and I'm getting response code 200 when testing against all of them). My code loops through and appends these individual URL's to the main Wikipedia URL. I've been able to get the heading of the page or other data, but what I really want is the Length of the song only

问题 I'm trying to fit my data to a user defined function using SciPy curve_fit, which works when fitting to a function with a fixed power (func1). But curve_fit does not work when the function contains a power as a parameter to fit to (func2). Curve_fit still does not work if I provide an initial guess for the parameters usins the keyword p0 . I can not use the bounds keyword as the version of SciPy which I have does not have it. This script illustrates the point: import scipy from scipy.optimize

问题 I have two computers, both running 64-bit Windows 7. One machine has python 32-bit, one is running python 64-bit. Both machines have 8GB of RAM. I'm using BeautifulSoup to scrape a webpage, but I've been running into issues on my python64 machine. I've been able to figure out that the output of my len(str(BeautifulSoup(request.get(http://www.sampleurl.com).text))) in 64bit is only returning 92520 characters but on the same, static, site on my python32-bit machine, it's returning 135000

问题 I'm trying to crawl this website, problem is it's dynamically loaded. Basically I want what I can see from the browser console, not what I see when I right click > show sources. I've tried some selenium examples but I can't get what I need. The code below uses selenium and get only what you get in right click -> show code. How can I get the content of the loaded page? from selenium.webdriver.support.ui import WebDriverWait from selenium.webdriver.support import expected_conditions as EC from

问题 How would I take my entries from Tkinter, concatenate them, and display them in the Label below (next to 'Input Excepted: ')? I have only been able to display them input in the python console running behind the GUI. Is there a way my InputExcept variable can be shown in the Label widget? from Tkinter import * master = Tk() master.geometry('200x90') master.title('Input Test') def UserName(): usrE1 = usrE.get() usrN2 = usrN.get() InputExcept = usrE1 + " " + usrN2 print InputExcept usrE = Entry
