Python Dicts - print the value rather than the key

maccored

Im missing something pretty simple Im assuming.

mydict = {'apple': 'non citrus', 'orange': 'non citrus', 'pear': 'non citrus', 'lime': 'citrus', 'plum': 'non citrus'}

Thats the dictionary.

I want to select those that are citrus. i can use the key (print (mydict ) ), but I would need to know which fruit was citrus first and have had the dict printed first so I could select.

How do I get it to select the key from the value, rather than the value from the key?

typical - spent days searching for an answer and the minute I put it up on boards, I find the solution:

print(list(mydict.keys())[list(mydict.values()).index('citrus')])

Your solution does work as it won't select all key, value, try 'non citrus' and you will only select orange...this  will select all key values of 'non citrus'
[font=Consolas, "Courier New", monospace]for key,value in mydict.items():
if value == 'non citrus':
print key[/font]

or a one liner

print '\n'.join([key for key,value in mydict.items() if value == 'citrus'])

All I noticed was that you had orange as non-citrus :eek:
