Always Show 4 Decimal Places

无人久伴 提交于 2020-01-24 12:42:07
问题 Is it possible to force a cell to always show 4 decimal places using xlwt? Regardless of the number actually present after the decimal place. I have done some searching and I can find a string to always reduce to 2 decimal places, but I need certain cells on my sheet to show 4. 回答1: Use xlwt styles. Here's a simple example: import xlwt book = xlwt.Workbook() sheet = book.add_sheet("test") decimal_style = xlwt.XFStyle() decimal_style.num_format_str = '0.0000' sheet.write(0, 0, 1.23456789,

Setting Cell Formats with xlwt format strings

问题 I've looked around for several different xlwt formats for cells, but I can't find a comprehensive list. Excel provides the following options for cell content formatting: (general, number, currency, accounting, date, time, percentage, fraction, scientific, text, special, custom) Obviously custom isn't what I want, but what are the formatting strings for all these different options? For example, I've seen: date_format = XFStyle() date_format.num_format_str = 'dd/mm/yyyy' currency_format =

问题 I am trying to use xlwt to create a output file (in .xlsx format) with multiple tabs. The version number of my Python is 2.7, and I am using Aptana Studio 3 as IDE. I've used the xlwt package before, with the same environment, to carry out the same task. It worked well. But this time, it works well at first, then suddenly, the output file became faulty that cannot be opened by MS Excel. Here is a clue that might be helpful. My Aptana Studio 3 decide to open .xlsx in its own editor rather than

问题 I am writing a python program to process .hdf files, I would like to output this data to an excel spreadsheet. I put the data into an array as shown below: Code: data = [] for rec in hdfFile[:]: data.append(rec) from here I have created a 2D array with 9 columns and 171 rows. I am looking for a way to iterate through this array and write each entry in order to a sheet. I am wondering if If I should create a list instead, or how to do this with the array I have created. Any help would be

问题 I'm trying to write data to an excel file that includes Japanese characters. I'm using codec.open() to get the data, and that seems to work fine, but I run into this error when I try to write the data: UnicodeEncodeError: 'ascii' codec can't encode characters in position 16-17: ordinal not in range(128) I don't understand why the program would be insisting on using ascii here. When I created a new workbook object, I did so using wb = xlwt.Workbook(encoding='utf-8') and both the program file

Conditional Formatting xlwt

问题 I have seen some posts that say you can NOT perform conditional formatting using xlwt , but they were rather old. I was curious if this has evolved? I have been searching for about half a day now. Furthermore, if I con't write it directly from xlwt , can I create an .xls file containing a single cell with the conditional format I want and have xlrd read that format and paste it into the sheet I aim to produce then using xlwt ? 回答1: xlrd and xlwt still don't support conditional formatting .
