Why is the value of the first key "apple" deleted in the dictionary?

Question

pairs = {1 : "apple",
"orange" : [2, 3, 4],
True : False,
12 : "True",
}

print(pairs.get("orange"))
print(pairs.get(7, 42))
print(pairs.get(12345, "not found"))
pairs.pop('orange')
print(pairs)

Answer 1

Ok let me try again. At first, your dictionary is given this key:value pair...
1:"apple"

and then it is given this key and value...
True:False

But the second assignment is actually saying this...
1:False
(since boolean True is the same as 1)

So, you have now done two assignments of a value to the SAME key in the SAME dictionary; therefore the 2nd assignment OVERWRITES the first. That is, the value (for the key of 1) is no longer "apple" but is now False.

There is no such thing as a key of True, distinct from a key of 1. Those are just two ways of indicating the same key.

Answer 2

1 == True, so apple will be overwritten with False

Answer 3

1 : "apple" #here 1 evaluates to True . True : "apple" like this.

True : false #as 1 evaluates to True . so now changing the value of key True will override the value of 1

So at last value of 1 is False

Answer 4

1: "apple" will be overwritten by True: False or 1: False if you want to put it like that

Answer 5

1 is the same as True, keys must be unique, so 'apple' will be overwritten by the following False

Let me be very very clear.
What I understand:
1) 1 is equal to True, and 0 is equal to False.
2) I understand that Python will read 1 as True.

What I don't understand:
1) Why Python also changed "apple" to False? Why cant it be - True: "apple" ?
What is the reason behind changing apple to False?

Answer 7

False comes after "apple" there "apple" is overwritten by False

Answer 8

You are assigning a value twice to the SAME key (that is, 1). So the first value (apple) gets replaced by the new value (False) from the second assignment.

1 and True are not distinct keys, because as you noted, they have the same hash value, so they are two ways of writing the same thing.

My doubt is solved! Thank you very much guys for your time. I appreciate it ❤️

Answer 10

Lisa If 1 == True, why would apple be overwritten?

Answer 11

TOLUENE 1) Why changing the value of key will override it's value also?
2) Why can't it be: True : "apple" ?
3) Why it changes the key to True? Why can't it be an integer 1?

Answer 12

Lisa I still don't get it.
I understand that 1 and True has same hash values.
What I don't understand is, why "apple" needs to be overwritten with False? Why can't it be just "apple" ?
