check if an item exists in a dictionary. if yes, delete it, otherwise add it

[joji00]

hi, im having a little problem here.
i want to check if an item exists in a dictionary, if yes, i have to delete it. otherwise i have to add it.

d = {'1':2}
 
if '1' not in d.items():
    d = {'1':2}
else:
    del (d['1'])
 
print (d)
 

but it seems wrong. i only just started so help would be greatly appreciated. thanks!

Adding, changing and deleting items from a dictionary is in most basic tutorials. Tutorials are write once, read many, so people don't have to answer the same basic questions over and over https://wiki.python.org/moin/BeginnersGuide/Programmers

I quite tryed to figure it out, im still a begginer but i've done this! Hope it helps :)

d = {'1':2}
d2 = {'1':2}
if d != d2:
    d['1']= 2
else:
    del (d['1'])
print d
