openpyxl

路由表一般是用Excel格式来编写的。因此需要用到openpyxl模块。 每个Excel文档打开之后可以抽象为一个workbook（工作簿），每个工作簿下面又有很多的sheet（工作表），sheet里面又有很多的Cell（表格），cell又可以组成行和列。 首先看怎么打开一个Excel文档： from openpyxl import load_workbook wb = load_workbook(filename = 'empty_book.xlsx') sheet=wb.get_sheet_by_name('RoutingTable') for row in sheet.rows: for cell in row: print(cell.value) 然后遍历一下所有cell的内容。 来源： https://www.cnblogs.com/ichbinhere/p/11746140.html

I am reading a column from an excel file using openpyxl. I have written code to get the column of data I need into excel but the data is separated by empty cells. I want to group these data wherever the cell value is not None into 19 sets of countries so that I can use it later to calculate the mean and standard deviation for the 19 countries. I don't want to hard code it using list slices. Instead I want to save these integers to a list or list of lists using a loop but im not sure how to because this is my first project with Python. Here's my code: #Read PCT rankings project ratified results

I'm using openpyxl to write to an existing file and everything works fine. However after the data is saved on the file, graphs disappear. I understand Openpyxl currently only supports chart creation within a worksheet only. Charts in existing workbooks will be lost. Are there any alternate libraries in Python to achieve this. I just want to feed a few values, so all the graphs and calculation happen in excel. Thank you. This is currently (version 2.2) not possible. I got some alternative solution to execute excel macro from python, that might be the solution for the above problem. Create a

Given the following as the contents of the first sheet of an xlsx roi.xlsx: Then: wb = load_workbook('roi.xlsx', data_only=True) ws=wb.worksheets[0] keynames = [i.value for i in ws.columns[0]] I want to add values into column B from the following dict: mydict = {'carnival': 2, 'festival': 3} When I try: for k, v in mydict.items(): keyPosition = keynames.index(k) ws.cell(row = keyPosition, column = 2).value = v I end up with a new column B, but empty values throughout, AND when I go to re-open the file after saving it with wb.save, Excel can't open the file because it is corrupted. I think the

Using openpyxl, the charts inserted into my worksheet have a border on them. Is there any way to set the style of the chart (pie/bar) to either via the styles.Style/styles.borders module to have no border, or at least a thin white border so that they would print borderless? The only options I see on the object is .style = <int> which doesn't seem to actually affect the design of the final graphic. seamus.shi You can set chat graphical_properties, the code is chart.graphical_properties = GraphicalProperties(ln=LineProperties(noFill=True)) This will apply the line style to chartSpace. Before you

I would like to change the background color of Chart_area as well as remove all borders. Regarding the background color, I have tried the solution suggested: How to set Background Color of Plot Area of Chart using openpyxl but this solution doesn't work for any charts i.e. BarChart, AreaChart, LineChart, ScatterChart, RadarChart etc... I tried two openpyxl versions: 2.4.7, 2.4.9. without success. # setup the chart chart = LineChart() # test to remove border line ***************************************************** chart.graphical_properties = GraphicalProperties(ln=LineProperties(noFill=True)

My code is following. import csv import openpyxl import sys def convert(input_path, output_path): """ Read a csv file (with no quoting), and save its contents in an excel file. """ wb = openpyxl.Workbook() ws = wb.worksheets[0] with open(input_path) as f: reader = csv.reader(f, delimiter='\t', quoting=csv.QUOTE_NONE) for row_index, row in enumerate(reader): for col_index, value in enumerate(row): ws.cell(row=row_index, column=col_index).value = value wb.save(output_path) def main(): try: input_path, output_path = sys.argv[1:] except ValueError: print 'Usage: python %s input_path output_path' %

python: extract float from a python list of string( AUD 31.99). I used openpyxl to read from an excel file the amount list. and i saved it in a list but the list is in string form like this: ['31.40 AUD', ' 32.99 AUD', '37.24 AUD'] I need to get the float from the string item list so that i can later save it in a new list to get the total of them. Desired output: [31.40, 32.99, 37.24] I have already tried these: newList = re.findall("\d+\.\d+", tot[0]) print(newList) Output: [31.40] But How can I use this for all the item elements? I am new to python, this is just for some work i do, wanted to
