| Examples |
element_names = {'H': 'hydrogen', 'He': 'helium', 'Li': 'lithium'}
# Iterate over each item of the dictionary:
for k, val in element_names.iteritems():
print("The name of element " + k + " is " + val)
| ||
| Description |
Returns tuples of the key/value pairs present in the specified dictionary, in
the form of an iterator. This iterator is primarily useful as a means of
iterating over every key/value pair in a dictionary in a for loop, as
shown in the example above. The iteritems() method is more memory-efficient than the items() method, as it returns each item in succession, instead of reproducing the entire dictionary as a list in memory. Note that because of the nature of the dictionary data structure, key/value pairs returned from iteritems() will be in arbitrary order (not necessarily the order they appeared in when the dictionary was defined). |
