python-3.x

问题 Suppose I have a list of numbers mylist and that I would like execute some code if all the elements of mylist are greater than 10. I might try if mylist[0] > 10 and mylist[1] > 10 and ... : do something but this is obviously very cumbersome. I was wondering if Python has a way of compressing multiple conditions in an if statement. I tried if mylist[i] > 10 for i in range(len(mylist)): do something but this returned an error. I am using Python 3.4. 回答1: Your attempt is pretty close. You just

问题 I'm trying to write a Python program that takes multiple binary files from LabView, selected and opened from a tkinter dialog box, and converts them to readable text files (or csv files, ideally). However, I'm having trouble with the binary to text conversion. Things I've tried looking at the binascii module. It doesn't appear clear to me that you can use this module to convert multiple-page files, only short strings. So, now, I'm thinking I should just open the file in utf-8 encoding and

问题 I'm trying to generate a bokeh application which allows the user to change the glyphs of a plot. Unfortunately, the glyphs don't change after calling on_change() method of the dropdown button although I'm able to change the axis label in a similar way. However, changing plot.glyph outside of the called function works fine. from bokeh.layouts import layout from bokeh.models import ColumnDataSource from bokeh.models.widgets import Dropdown from bokeh.plotting import figure from bokeh.io import

问题 There are many situations where the user's language is not a " latin " script (examples include: Greek, Russian, Chinese). In most of these cases a sorting is done by first sorting the special characters and numbers (numbers in local language though...), secondly the words in the local language-script at the end, any non native characters such as French, English or German "imported" words, in a general utf collation. Or even more specific for the rest...: is it possible to select the sort
