Do you REALLY know Python? 90% of Beginners Fail This
Most Python beginners get this WRONG! 🤯🐍
Can you guess the output before the video ends? This is one of Python's most famous "gotchas" involving mutable default arguments.
Why does this happen? In Python, default arguments are evaluated only ONCE at the time of function definition, not every time the function is called. So, that empty list [] is the same object across all calls!
