python traverse dictionary code example
Example 1: python iterate dictionary key value
a_dict = {'color': 'blue', 'fruit': 'apple', 'pet': 'dog'}
for key, value in a_dict.items():
print(key, '->', value)
Example 2: python loop through dictionary
dictionary = {52:"E",126:"A",134:"B",188:"C",189:"D"}
for key, value in dictionary.items():
print(key)
print(value)
Example 3: python iterate through dictionary
a_dict = {'apple':'red', 'grass':'green', 'sky':'blue'}
for key in a_dict:
print key # for the keys
print a_dict[key] # for the values
Example 4: iterate through dictionary
#iterate the dict by keys
for key in a_dict:
print(key)
#iterate the dict by items - (key,value)
for item in a_dict.items():
print(item)
#iterate the dict by values
for value in a_dict.values():
print(value)
Example 5: python loop through dictionary
new_list = [something(key, value) for key, value in a_dict.items()]
Example 6: python loop through dictionary
d = {'x': 1, 'y': 2, 'z': 3}
for key in d:
print key, 'corresponds to', d[key]
