how to iterate a dictionary in python 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: 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 3: python loop through dictionary
new_list = [something(key, value) for key, value in a_dict.items()]
Example 4: loop throughthe key and the values of a dict in python
a_dict = {"color": "blue", "fruit": "apple", "pet": "dog"}
# Will loop through the dict's elements (key, value) WITHOUT ORDER
for key, value in a_dict.items():
print(key, '->', value)
Example 5: python loop through dictionary
d = {'x': 1, 'y': 2, 'z': 3}
for key in d:
print key, 'corresponds to', d[key]
Example 6: for key value in dict python
a_dict = {"color": "blue", "fruit": "apple", "pet": "dog"}
for key in a_dict:
print(key, '->', a_dict[key])
# Output:
# color -> blue
# fruit -> apple
# pet -> dog
