 the value of t in the code shown above is equal to 32.00, which is a floating point value. ‘float’ objects are not iterable. hence the code results in an error.

 execute in the shell to verify.

 the values of a dictionary can be accessed using keys but the keys of a dictionary can’t be accessed using values.

 option c is a set, not a dictionary.

 the get() method returns the value of the key if the key is present in the dictionary and the default value(second parameter) if the key isn’t present in the dictionary.

 the get() method returns the default value(second parameter) if the key isn’t present in the dictionary.

 setdefault() will set dict[key]=default if key is not already in the dictionary.

 keys of a dictionary may be any data type that is immutable.

 pop() method removes the key- value pair for the key mentioned in the pop() method.
