Can anyone explain the output of the below mentioned code??
my_dict = {True:'yes',1:'no',1.0:'maybe'} print(my_dict) Output: { True : 'maybe'} I'm not able to understand why the entire dictionary is not printed as the output

It is actually pretty confusing due to the fact that you are using keywords and mixing integers with decimals.
Python does a lot of stuff the way it wants it to. I would prefer a more explicit definition.
Try using keys and values that you can easily follow, like names and ages.

I think dictionaries filter their key duplicates by their equality.

Thank you for your explanation... But i'm still confused😅
Why the keyword True is printed with output 'maybe' and not with its original value 'yes' ?!

Actually this question was asked in a challenge... But I agree that booleans should not be used as keys in a dictionary.

SC Sharma it could be because you 1.0:'maybe' was put there later and program treated it as reassigning to True:'yes', because 1.0 == True.

It's a terrible question hahah. You can use online python compilers to try the challenges later

Try this format (released is the dict).
released = {
"iphone 3G" : 2008,
"iphone 3GS" : 2009,
"iphone 4" : 2010,
"iphone 4S" : 2011,
"iphone 5" : 2012
}
print(released) # Outputs all keys and values
print(len(released)) # Outputs 5
print("iphone" in released) # Prints False
print("iphone 5" in released) # Prints True
