Answer to Question #305884 in Python for Michael

Question

Write a python function Write_String(fanme, *list) which take a list containing string elements and write them in a file myfile.txt until the string “finish” (not case sensitive) occur. The function then returns the contents written in file as a string. Before writing list elements in file, you also need to make a separate python function to check whether input list contains "Finish" or not. If not, then it should return error as shown in example.

myfile.txt:

Python

Java

C

C++

Ruby

.Net
