AWS Lambda python directory Easter Egg

Posted on by

This could be  a bug or an Easter Egg in AWS Lambda. When you create directories “py” and “python”, directory “thon” appears in the Lambda Console code tree. Directory “thon” does not actually exist.

Setup

[ec2-user@ip-172-31-80-17 EasterEgg]$ mkdir py python
[ec2-user@ip-172-31-80-17 EasterEgg]$ cat > lam.py
from os import system

def lam(e,c):
    system('du')
    return {}
[ec2-user@ip-172-31-80-17 EasterEgg]$ zip -rq ../EasterEgg.zip *
[ec2-user@ip-172-31-80-17 EasterEgg]$ aws lambda update-function-code 
  --function-name EasterEgg 
  --zip-file fileb://../EasterEgg.zip

Result

Directory “thon” appears in the code tree.. du output shows that directory “thon” does not exist.
