Using a third-party package of your choice, write a program that reads the contents of a csv file and saves it to an Excel file. The program should take two arguments. The name of the input file and the name of the output file.

import pandas as pd

df = pd.read_csv("file_csv")

df.to_excel("file.xlsx", sheet_name = "name_of_sheet")

# or use: with df.ExcelWriter("file.xlsx", mode='a') as file,

#df.to_excel(file, sheet_name= "sheet name")

Explanation:

This python source code uses the pandas package to read csv (comma separated values) file and converts it to an excel file (xlsx) using the read_csv and ExcelWriter methods respectively.
