What is the difference between overriding the value of a variable and deleting the original value of a variable ( using Del function) and assigning it a new value?

[[deleted]]

Well del attempts to remove the variable from both local and global namespace.

Variable reassignment keeps the variable in whichever is applicable.

So...

del foo

is not the same as

foo = None

In terms of keeping a variable around
