How to delete a global variable from inside a function?

Question

I have a global variable ser which I need to delete under certain circumstances:

global ser
ser = [\'some\', \'stuff\']

def reset_ser():
    pr         


        

Answer 1

Just use global ser inside the function:

ser = "foo"
def reset_ser():
    global ser
    del ser

print(ser)
reset_ser()
print(ser)

Output:

foo
Traceback (most recent call last):
  File "test.py", line 8, in 
    print(ser)
NameError: name 'ser' is not defined
