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

Answer 2

# Define path to excel file
path = os.path.dirname(os.path.abspath(__file__))

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

The above code snippet fixed the Exception has occurred: com_error issue I was running into.
