 Live Demo

my_dict ={"Hi":100, "there":121, "Mark":189}
print("The dictionary is :")
print(my_dict)

dict_key = list(my_dict.keys())
print("The keys in the dictionary are :")
print(dict_key)
dict_val = list(my_dict.values())
print("The values in the dictionary are :")
print(dict_val)

my_position = dict_val.index(100)
print("The value at position 100 is : ")
print(dict_key[my_position])

my_position = dict_val.index(189)
print("The value at position 189 is")
print(dict_key[my_position])

Output

The dictionary is :
{'Hi': 100, 'there': 121, 'Mark': 189}
The keys in the dictionary are :
['Hi', 'there', 'Mark']
The values in the dictionary are :
[100, 121, 189]
The value at position 100 is :
Hi
The value at position 189 is
Mark
