not able to pass parameter to function in python

Question

How to convert below python code into function, so that when i call and pass parameter the function process and run

Pyhton code:

import pandas as pd
data_xls = pd.read_excel('/demo/ab/excelfile.xlsx', 'Sheet1', dtype=str, index_col=None)
data_xls.to_csv('csvfile.csv', encoding='utf-8', index=False)

I need like below:

def pyconv(function):
    var=path
    fname=filename
    import pandas as pd
    data_xls = pd.read_excel('var', 'fname', dtype=str, index_col=None)
    data_xls.to_csv('csvfile.csv', encoding='utf-8', index=False)

when i call function and pass parameter it should run:

pycon(path,filename)

my function will take var value: '/demo/ab/excelfile.xlsx' and fname=sheet1

pycon('/demo/ab/excelfile.xlsx','sheet1')

Answer 1

def pycon(path,sheet):
  import pandas as pd
  data_xls = pd.read_excel(path,sheet, dtype=str, index_col=None)
  data_xls.to_csv('csvfile.csv', encoding='utf-8', index=False)

and now this shall work

pycon(r'/demo/ab/excelfile.xlsx','sheet1')
