python – How to print Specific key value from a dictionary?

Pythons dictionaries have no order, so indexing like you are suggesting (fruits[2]) makes no sense as you cant retrieve the second element of something that has no order. They are merely sets of key:value pairs.

To retrieve the value at key: kiwi, simply do: fruit[kiwi]. This is the most fundamental way to access the value of a certain key. See the documentation for further clarification.

And passing that into a print() call would actually give you an output:

print(fruit[kiwi])
#2.0

---

Note how the 2.00 is reduced to 2.0, this is because superfluous zeroes are removed.

---

Finally, if you want to use a for-loop (dont know why you would, they are significantly more inefficient in this case (O(n) vs O(1) for straight lookup)) then you can do the following:

for k, v in fruit.items():
    if k == kiwi:
        print(v)
#2.0

fruit = {
    banana: 1.00,
    apple: 1.53,
    kiwi: 2.00,
    avocado: 3.23,
    mango: 2.33,
    pineapple: 1.44,
    strawberries: 1.95,
    melon: 2.34,
    grapes: 0.98
}

for key,value in fruit.items():
    if value == 2.00:
         print(key)

I think you are looking for something like this.

Its too late but none of the answer mentioned about dict.get() method

>>> print(fruit.get(kiwi))
2.0

In dict.get() method you can also pass default value if key not exist in the dictionary it will return default value. If default value is not specified then it will return None.

>>> print(fruit.get(cherry, 99))
99

fruit dictionary doesnt have key named cherry so dict.get() method returns default value 99
