Question

Given a variable, unproved_conjectures, that is associated with a dictionary that maps the common names of mathematical conjectures to the years when the conjectures were made, write a statement that deletes the entry for "Fermat's Last Theorem".

Answer 1

#! /usr/bin/python3

#creating a dictionary for unproved_conjectures
unproved_conjectures = dict()

#creating entry for "Fermat's Last Theorem" in unproved_conjectures
unproved_conjectures["Fermat's Last Theorem"] = "year: 1637"

#Check if there is an entry for Fermat's Last Theorem, if it exists then delete that entry
if "Fermat's Last Theorem" in unproved_conjectures:
    del unproved_conjectures["Fermat's Last Theorem"]
    print("Entry for Fermat's Last Theorem has been successfully removed from unproved_conjectures")
else:
    print("Entry for Fermat's Last Theorem doesn't exist")
