format

问题 I'm working on an APA citation maker in Python using tkinter. I use the Text widget to display the citation once it's generated, but whenever I copy the text (using the ctrl+c shortcut, at the moment) it loses its formatting. Is there some way to copy formatted text (italicized, for instance) from the Text widget rather than unformatted text? 回答1: To copy formatted text to the clipboard, you need an interface between python and the system's clipboard which supports text formatting. I have

问题 I'm looking for a way to pad the float decimals with zeros: This one is my reference: In [37]: '{:5.5}'.format(round(4.123456, 5)) Out[37]: '4.1235' I have this: In [38]: '{:5.5}'.format(4.1) Out[38]: ' 4.1' But I would like to have this: Out[38]: '4.1000' 回答1: To format a floating point number with a given precision you should use the 'f' specifier. Without it the value is formatted as a string. >>> '{:.4f}'.format(4.1) '4.1000 You can also specify the minimum width of the complete output

问题 I'm integrating two poorly documented systems, and in the process I've come across a strange data format I haven't seen before. It's stored as plain text in the db with no indication as to what the format is and how to deal with it. a:17:{s:2:"id";s:27:"145219921F990B11C39E7220000";s:16:"purchase_country";s:2:"no";s:17:"purchase_currency";s:3:"nok";s:6:"locale";s:5:"nb-no";s:6:"status";s:17:"checkout_complete";s:9:"reference";s:27:"145212221F990B11C39E7221000";s:11:"reservation";s:10:

问题 I am developing an application in C# so whereby, if the user confirms a messagebox to formatting a USB drive, selected from a combobox list, the drive will be formatted. I haven't got an idea how to approach this, however - I have the following code: public static bool FormatDrive(string driveLetter, string fileSystem = "FAT", bool quickFormat = false, int clusterSize = 4096, string label = "", bool enableCompression = false) { if (driveLetter.Length != 2 || driveLetter[1] != ':' || !char

问题 I cant use the .centroid() method because its returns [NaN,Nan]. I dont know what is the right data format. var pathh = d3.geo.path(); d3.selectAll("path.line") .each(function (d, i) { var centroid = pathh.centroid(d); console.log('Centroid at: ', d,+ centroid[0] + ', ' + centroid[1]); }); My data format is: One object is one point(vertex) of the polygon 0: Object area_id: "IVP001" vertex_id: "37451" x: "100" y: "100" 1: Object area_id: "IVP001" vertex_id: "37452" x: "150" y: "120" 2: Object

问题 Is there any tricky way to format seconds like hours:minutes:seconds. For example, 3660 seconds will be displayed as 01h 01m 00s or 01:01:00 I am aware of the standard way of doing this: Divide all seconds on 3600 to get the hours Divide the rest seconds on 60 to get the minutes The rest are the seconds I met the following issues: I am not able to create separate function that do this. My code is in view using several CTEs. So, variables can be declare using the CTEs only. I am not able to

问题 Hallo I try to create a decisiontree with my csv datasheet. I installed in anaconda and python the graphviz package with the following command: conda install graphviz pip install graphviz to get my tree visible. Here is my code that I have wrote in Jupyther Notebook: import pandas as pd import graphviz from sklearn import metrics from sklearn.tree import DecisionTreeClassifier, export_graphviz from sklearn.model_selection import train_test_split file = 'automotive_data.csv' COLS = np.arange(0
