Get key by value in dictionary
Posted By: Anonymous
I made a function which will look up ages in a Dictionary
and show the matching name:
dictionary = {'george' : 16, 'amber' : 19}
search_age = raw_input("Provide age")
for age in dictionary.values():
if age == search_age:
name = dictionary[age]
print name
I know how to compare and find the age I just don’t know how to show the name of the person. Additionally, I am getting a KeyError
because of line 5. I know it’s not correct but I can’t figure out how to make it search backwards.
Solution
There is none. dict
is not intended to be used this way.
dictionary = {'george': 16, 'amber': 19}
search_age = input("Provide age")
for name, age in dictionary.items(): # for name, age in dictionary.iteritems(): (for Python 2.x)
if age == search_age:
print(name)
