使用 xlsxwriter returns 将图像写入 excel “工作簿不可调用”
writing image to excel with xlsxwriter returns " workbook not callable"
使用以下 link 的第一个答案作为指导：
我有以下脚本，我想在其中将数据框对象写入一个 sheet 并将一堆图像写入另一个 sheet。
class name():
def some_func(self):
self.writer = pd.ExcelWriter('Name1',engine='xlsxwriter')
return
def write_excel(self):
self.df.to_excel(self.writer,sheet_name='Name',index=False, header=False)
self.writer.save()
return
def write_excel(self):
self.workbook = self.writer.book('Name1')
self.worksheet = self.writer.sheets(name='images')
images=[]
do some stuff
for i,image in enumerate(images):
self.worksheet.insert_image('D1',0,y_postn[i],image)
self.writer.save()
return
就是returns下面的错误
'Workbook' object is not callable
不确定如何解释或修复此错误？...
错误来自这一行：
self.workbook = self.writer.book('Name1')
Book 是一个对象，而不是方法，它具有以下字段（__call__ 不是其中之一）：

这里有官方的例子来说明如何使用这个API：
# Get the xlsxwriter objects from the dataframe writer object.
workbook = writer.book
worksheet = writer.sheets['Sheet1']
# Create a chart object.
chart = workbook.add_chart({'type': 'column'})
# Get the dimensions of the dataframe.
(max_row, max_col) = df.shape
# Configure the series of the chart from the dataframe data.
chart.add_series({'values': ['Sheet1', 1, 1, max_row, 1]})
# Insert the chart into the worksheet.
worksheet.insert_chart(1, 3, chart)
您不应该像调用函数一样调用工作簿或工作表。您可以访问其中的函数，例如 .add_chart 或 .insert_chart.
首先，您是如何获得包含书籍和表格的电子表格的？像这样：
# Create a Pandas dataframe from the data.
df = pd.DataFrame({'Data': [10, 20, 30, 20, 15, 30, 45]})
# Create a Pandas Excel writer using XlsxWriter as the engine.
writer = pd.ExcelWriter('pandas_simple.xlsx', engine='xlsxwriter')
# Convert the dataframe to an XlsxWriter Excel object.
df.to_excel(writer, sheet_name='Sheet1')
# Get the xlsxwriter objects from the dataframe writer object.
workbook = writer.book
worksheet = writer.sheets['Sheet1']
您还可以选择直接访问 xlswriter APIs 而无需通过 pandas（但我不明白为什么在您的特定情况下会这样做）：
workbook = xlsxwriter.Workbook('filename.xlsx')
worksheet = workbook.add_worksheet()
看看 official documentation - 里面有很多清晰的例子。
