print(type(x), '\n')
print('Check!')
print('y =',y)
x = []
<class 'list'>
Check!
y = []

Using [ ]:
# Create a list

# Output
print('x =',x)
print(type(x), '\n')
print('Check!')
print('y =',y)
x = []
<class 'list'>
Check!
y = [1, 2, 3]

Using del:
# Create a list
x = [1,2,3]
y = x # reference
# Clear

# Output
print('x =',x)
print(type(x), '\n')
print('Check!')
print('y =',y)
x = []
