Using the first answer to the following link Python: Writing Images and dataframes to the same excel file as a guide:

I have the following script in which I like to write a dataframe object to one sheet and a bunch of images to another 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

It returns the following error

'Workbook' object is not callable

Not sure how to interpret this error or fix it?...

CodePudding user response：

The error comes from this line:

self.workbook = self.writer.book('Name1')

Book is an object, not a method and it has the following fields (__call__ is not one of them):

Here's the official example for how to use this 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)

You are not supposed to call workbooks or sheets as if they are functions. You access functions within them such as .add_chart or .insert_chart.

How do you get your hands on a spreadsheet with books and sheets in it in the first place? Like this:

# 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']

You also have the option of accessing the xlswriter APIs directly without going through pandas (but I don't see why you would in your particular case):

workbook  = xlsxwriter.Workbook('filename.xlsx')
worksheet = workbook.add_worksheet()

Have a look at the official documentation - it's full of clear examples.
