(b) Write the output of the following code:

Answer 1

Given dictionary:

mon = {'Jan':31, 'Feb':28, 'Mar':31, 'April':30}

(a) Given statements:

• (i) print(mon['Jan'])
• (ii) print(mon [28])

The incorrect statement will be (ii) print(mon[28]) since there is no key by the name '28' in the given dictionary.

(b)

>>> mon["Feb"] = 29

#adds a new key 'Feb' with the value 29 into the dictionary, 'mon'.

>>> print(mon)

{'Jan': 31, 'Feb': 29, 'Mar': 31, 'April': 30}

>>> del mon["April"]

#deletes the key 'April' from the dictionary 'mon'.

>>> print(mon)

{'Jan': 31, 'Feb': 29, 'Mar': 31}

>>> mon.clear()

#clears the elements in the dictionary, making it an empty dictionary.

>>> print(mon)​

{}
