However, you can use the keyboard shortcut key Ctrl + P to open the print window on a PC or Command + P to open the print window on an Apple computer.
To print dictionary items: key:value pairs, keys, or values, you can use an iterator for the corresponding key:value pairs, keys, or values, using dict. items(), dict. keys(), or dict. values() respectively and call print() function.
A dictionary has, by definition, an arbitrary number of keys. There is no "the key". You have the keys()
method, which gives you a python list
of all the keys, and you have the iteritems()
method, which returns key-value pairs, so
for key, value in mydic.iteritems() :
print key, value
Python 3 version:
for key, value in mydic.items() :
print (key, value)
So you have a handle on the keys, but they only really mean sense if coupled to a value. I hope I have understood your question.
Additionally you can use....
print(dictionary.items()) #prints keys and values
print(dictionary.keys()) #prints keys
print(dictionary.values()) #prints values
Hmm, I think that what you might be wanting to do is print all the keys in the dictionary and their respective values?
If so you want the following:
for key in mydic:
print "the key name is" + key + "and its value is" + mydic[key]
Make sure you use +'s instead of ,' as well. The comma will put each of those items on a separate line I think, where as plus will put them on the same line.
dic = {"key 1":"value 1","key b":"value b"}
#print the keys:
for key in dic:
print key
#print the values:
for value in dic.itervalues():
print value
#print key and values
for key, value in dic.iteritems():
print key, value
Note:In Python 3, dic.iteritems() was renamed as dic.items()
