## Code Before:

def main():
    command = ""
    while command != "exit":
        command = input("> ").strip()

if __name__ == "__main__":
    main()


## Instruction:
Read files defined as argument
## Code After:

import sys 

def main():
    if len(sys.argv) > 1: 
        for i in range(1, len(sys.argv)):
            with open(sys.argv[i]) as f:
                lines = f.read().splitlines()
                for line in lines:
                    evaluate(line);

    command = ""
    while command != "exit":
        command = input("> ").strip()

def evaluate(string):
    print(string)

if __name__ == "__main__":
    main()
