 Pandas - Write to Exisitng Excel File - Sorted List
hi friends

how can i write my sorted list to an exisitng excel file ie sheet name and column number

from openpyxl import load_workbook
import pandas as pd
from pandas import ExcelWriter
from pandas import ExcelFile
df = pd.read_excel('python.xlsx', sheet_name='Sheet1')

z= list(df.names)                                                    #Column Name is imported into a List  >  ['Sean', 'Joyce', 'Ruby', 'Pamela']




thank you for your help

Well without seeing the error its hard to say what the problem is. I would start debugging by checking the type of what your trying to write to make sure its what to_excel() function is expecting. I am not sure what exactly it is you are trying to do. It seems as thought you are attempting to take the Column names from python.xlsx, sort them and write them to a different excel file; is that correct?

I have never used Pandas or messed with excel files before but I can tell you this much; to_excel() is expecting type ExcelWriter ie:

# Specify a writer
writer = pd.ExcelWriter('example.xlsx', engine='xlsxwriter')

# Write your DataFrame to a file     
yourData.to_excel(writer, 'Sheet1')

# Save the result

thank you for your help

I included the new code
but an error came up

z.to_excel(writer, 'Sheet1')
AttributeError: 'list' object has no attribute 'to_excel'

Yes i wanted to output my sorted list into an excel file

Sure, that error makes sense right because z is a list where to_excel() only works on ExcelWriter() type. So just pack it back into the proper type. The sooner you learn to start type checking and figuring out what the functions your attempting to use are expecting (in terms of type) the better.

is there an example that can show me how to type cast, i have not been able to find anything.
That applie to my example.
I sorted my list
I just want to write my list to excel sheet now
