how to loop through 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: 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: 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)
