Python help w/ .txt file

[chicks4]

1. Hi so my assignment asks that I use text saved under 'numbers.txt'
   
2. I am using Windows, so I used notepad to write the text and save it under the name
   
3. However, when I go to run the code, I get the error Errno 2 no such file or directory.
   

Here is the code I have.

def main():
    infile = open('numbers.txt', 'r')

    file_contents = infile.read()
    infile.close()

    print(file_contents)

main()

I hope I used the tags correctly!!! I am new!
