FileNotFoundError when load_workbook using the passed over filename

Question

I def a function and passed over its argument from a for loop, and got the FileNotFoundError: [Errno 2] No such file or directory: 'revenue.xlsx'.

The for loop works and the function also works when separately print them. So I am assuming something is wrong when passing over the argument.

Here's my entire code.

 import openpyxl as xl from openpyxl.chart import Reference, BarChart from pathlib import Path def process_workbook(file_name): wb = xl.load_workbook(file_name) sheet = wb['Sheet1'] for row in range(2, sheet.max_row + 1): cell = sheet.cell(row, 3) corrected_price = cell.value * 0.9 corrected_price_cell = sheet.cell(row, 4) corrected_price_cell.value = corrected_price data = Reference(sheet, min_col=4, min_row=2, max_row=sheet.max_row) cats = Reference(sheet, min_col=1, min_row=2, max_row=sheet.max_row) chart = BarChart() chart.add_data(data) chart.set_categories(cats) sheet.add_chart(chart, 'F2') wb.save(file_name) return file_name path = Path('/Users/yugao/Downloads/Python Tutorial Supplementary Materials') for file in path.glob('*.xlsx'): filename = file.name process_workbook(filename)

here's my error:

Answer 1

You need to supply the path to the file as well (me thinks).

filename=str(path)+'/'+filename
