Is there a way to do it the other way round
Given the value, can I get the variable name ?
(1) Yes you can in some cases.
(2) You should not, things do not inherently have a name.
With that prelude:
def find_names(value, dictionary):
for name, val in dictionary.items():
if val is value: # note: "is", not "=="
yield name
x = 123456
y = 123456 * 3 // 3
z = 123456.0
q = y
print list(find_names(y, locals()))
