Write a Python program to iterate over dictionaries using for loops code example

Example 1: 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 2: python loop through dictionary

d = {'x': 1, 'y': 2, 'z': 3} 
for key in d:
    print key, 'corresponds to', d[key]

Example 3: python generate dictionary in loop

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