People do get very jealous even if it doesn't affect them. I automated something similar in one of my grad school courses (image processing). Each assignment required a report to be generated in a particular format that showed all of the results from each step in the assignment. It could be very time consuming because if you made any adjustments to your code based on incorrect results in later steps, you would often have to go back and edit the entire report to reflect your changes. I wrote a script to automatically generate these reports as I worked on the assignment. If I made any changes to my code, I could generate a new report in seconds.

A student in my class looked over my shoulder and saw me run my script in the lab. I thought she was just going to ask if she could have a copy of it, but instead she angrily accused me of plagiarism. When I asked where I was supposedly plagiarizing from, she instead just accused me of cheating. She went up to our professor in class and demanded that I received no credit for the assignment. The grades in this class were not curved in any way, so my grade would have no impact on her's. Luckily, the professor just laughed at her and said "What? I'm supposed to give him an F for being smarter than you? Write your own damn script if it's that useful.".
