Let’s learn about the peculiar nature of Python dictionaries.

C++
some_dict = {}
some_dict[5.5] = "JavaScript"
some_dict[5.0] = "Ruby"
some_dict[5] = "Python"
print(some_dict[5.5])
print(some_dict[5.0]) # "Python" destroyed the existence of "Ruby"?
print(some_dict[5]) 
print("---------")
complex_five = 5 + 0j
print(type(complex_five))
print(some_dict[complex_five])



So, why is Python all over the place?

Explanation

  • Uniqueness of keys in a Python dictionary is by equivalence, not identity. So even though 5, 5.0, and 5 + 0j are distinct objects of
