In code, list.clear doesn't throw error - it's just ignored

[Weatherby,Gerard]

The terminal told you what x.clear was.

The Python documentation tells you how to call it: https://docs.python.org/3/tutorial/datastructures.html

list.clear()
Remove all items from the list. Equivalent to del a[:].

An IDE (e.g. PyCharm) will try to autocomplete the parentheses and warn you if you don’t:

“Statement seems to have no effect and can be replaced with a function call to have effect”

In code, list.clear is just ignored.
At the terminal, list.clear shows
<built-in method clear of list object at 0x000001C9CFEC4240>


in code:
x = [1,2,3]
x.clear
print(len(x))
3

at terminal:
x = [1,2,3]
x.clear
<built-in method clear of list object at 0x000001C9CFEC4240>
print(len(x))
3


Caused me an hour of frustration before I noticed list.clear() was what
I needed.

x = [1,2,3]
x.clear()
print(len(x))
0
