How to iterate over worksheets in workbook, openpyxl

问题

I've been using the openpyxl module to do some processing on some .xlsx files. I've been trying to figure out how to iterate over sheets in a workbook. I'm not sure if I can get it figured out. I've tried the 2 codes below which both return empty results. My .xlsx file has about 20 sheets, so something should return.

The one thing I couldn't find on the internet, is how to set a workbook to an actual workbook. Usually I am writing to a workbook, so I just initialize it by setting a variable to en empty workbook workbook = Workbook() but in this case, I am unsure if I can open a workbook by doing workbook = Workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")

If anyone can identify what it is I am doing wrong, I would appreciate it.

Here is my code:

workbook = Workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")

for sheet in workbook.worksheets:
    print sheet

# or

for sheet in workbook.worksheets:
    print sheet.title

回答1:

Open the workbook via load_workbook() and iterate over worksheets:

from openpyxl import load_workbook

wb = load_workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")

for sheet in wb.worksheets:
    print sheet

回答2:

To print titles of all sheets in a workbook:

from openpyxl import load_workbook

wb = load_workbook(r"C:\Excel\LOOKUP_TABLES_edited.xlsx")
print(wb.sheetnames)

回答3:

Here's one if you need active worksheets for your code

for sheet in wb:
    ws = wb[sheet]
    print('Now in sheet: ' + ws.title)
