Create an empty dictionary, add four keys and values to the dictionary. Print the keys from the dictionary. dic={} dic[‘O’]=”Oxyzen” dic[‘Ca’]=”Calcium” dic[‘Na’]=”Sodium” dic[‘H’]=”Hydrogen” print(dic) print(dic.keys())   Create a dictionary, dic={‘O’:’Oxyzen’,’Ca’:’Calcium’,’Na’:’Sodium’,’H’:’Hydrogen’}. Print the values from the dictionary. dic={‘O’:’Oxyzen’,’Ca’:’Calcium’,’Na’:’Sodium’,’H’:’Hydrogen’} print(dic) print(dic.values())   Create a dictionary, dic={‘O’:’Oxyzen’,’Ca’:’Calcium’,’Na’:’Sodium’,’H’:’Hydrogen’}. Print the items from the dictionary. dic={‘O’:’Oxyzen’,’Ca’:’Calcium’,’Na’:’Sodium’,’H’:’Hydrogen’} print(dic) print(dic.items())   4.Create a dictionary marks={‘maths’:97,’science’:98,’history’:78}. Remove the key science from the dictionary. marks={‘maths’:97,’science’:98,’history’:78} del marks[‘science’] print(marks)   Create a dictionary marks and clear all the items from the dictionary. marks={‘maths’:97,’science’:98,’history’:78} marks.clear() print(marks)   Create a dictionary, delete the dictionary and check whether the dictionary exists or not. … Continue reading Python Exercise3
