loop in python 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: 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 4: python generate dictionary in loop

n = int(input())
ans = {}
for i in range (1,n+1):
  ans[i] = i * i
print(ans)

Example 5: iterate through keys in dictionary

for key in dictionary_name:
