excel - Python xlsxwriter 模块 : Iterating through same set of format and conditions on multiple worksheets

Question

使用 xlsxwriter 模块，我创建了一个 Python 脚本，它将 csv 文件内容复制到 Excel 工作表。然后创建第二个工作表，其中包含查找、计算、条件格式 - 一个模板 - 基于第一个工作表。没问题。
当我尝试循环代码时，我的问题就开始了，即将 3 个 csv 文件内容复制到 1 个工作簿中的 3 个工作表中，然后再创建 3 个应用相同模板但基于不同工作表查找的工作表。这是“将 csv 复制到 excel 工作表”代码的片段:

workbook = Workbook(csvFile[:-4] + '.xlsx', {'strings_to_numbers': True})
align = workbook.add_format({'align':'center','text_wrap':True})
for csvfile in (glob.glob(filepath + '\\*.csv')):                
    worksheet = workbook.add_worksheet(header[2])
    with open(csvfile, 'rb') as f:
        reader = csv.reader(f)
        for r, row in enumerate(reader):
            for c, col in enumerate(row):
                worksheet.set_column('A:A',65)
                worksheet.set_column('B:P',12)
                worksheet.write(r, c, col, align)

我想做这样的事情:

workbook = Workbook(csvFile[:-4] + '.xlsx', {'strings_to_numbers': True})
align = workbook.add_format({'align':'center','text_wrap':True})
for i, csvfile in (glob.glob(filepath + '\\*.csv')):   
    worksheet[i] = workbook.add_worksheet(header[i])             
    with open(csvfile, 'rb') as f:
        reader = csv.reader(f)
        for r, row in enumerate(reader):
            for c, col in enumerate(row):
                worksheet[i].set_column('A:A',65)
                worksheet[i].set_column('B:P',12)
                worksheet[i].write(r, c, col, align)

xlsxwriter 模块不允许我这样做。上面的代码会抛出以下错误:

File "C:\workspace\automagic.py", line 103, in create_xls
worksheet[i] = workbook.add_worksheet(header[i]) 
NameError: global name 'worksheet' is not defined

我不想复制和粘贴相同的代码，只是更改了工作表名称。

更新:考虑到 jmcnamara 的评论，我能够修改我的代码，如下所示:

worksheet = ['worksheet0','worksheet1','worksheet2']
workbook = Workbook(csvFile[:-4] + '.xlsx', {'strings_to_numbers': True})
align = workbook.add_format({'align':'center','text_wrap':True})    

for i, csvfile in enumerate(glob.glob(filepath + '\\*.csv')):  
    testtype = csvfile.split('.')[3].split('_')[1]
    worksheet[i] = workbook.add_worksheet(testtype)
    with open(csvfile, 'rb') as f:
            reader = csv.reader(f)
            for r, row in enumerate(reader):
                for c, col in enumerate(row):
                    worksheet[i].set_column('A:A',65)
                    worksheet[i].set_column('B:P',12)
                    worksheet[i].write(r, c, col, align)  

Answer 1

xlsxwriter module doesn't allow me to do that. The code above would throw the following error

这不是 XlsxWriter 错误，而是一般的 python 错误。您会从以下内容中得到相同的错误:

$ cat error_test.py

def some_func():
    i = 1
    worksheet[i] = 123

some_func()


$ python error_test.py
Traceback (most recent call last):
  File "error_test.py", line 7, in <module>
    some_func()
  File "error_test.py", line 5, in some_func
    worksheet[i] = 123
NameError: global name 'worksheet' is not defined

您需要声明变量 worksheet某处，可能使用 worksheet.append()也是。
