#Using get()
my_dict = {'name': 'Kumar', 'age': 25}
print("Output for get:")
print(my_dict.get('name'))
print(my_dict.get('gender', 'Not Found'))
print()
#Using keys()

print("Output for keys:")
print(my_dict.keys())
print()

my_dict = {'a': 1, 'b': 2}
print("Output for values:")
print(my_dict.values())
print()
#Using items()
my_dict = {'a': 1, 'b': 2}
print("Output for items:")
print(my_dict.items())
print()
#Using update()
my_dict = {'a': 1}
my_dict.update({'b': 2, 'c': 3})
print("Output for update:")
print(my_dict)
print()
#Using pop()
my_dict = {'a': 1, 'b': 2}
value = my_dict.pop('a')
print("Output for pop:")
print(value)
print(my_dict)
print()
#Using popitem()
my_dict = {'a': 1, 'b': 2}
item = my_dict.popitem()
print("Output for popitem:")
print(item)
print(my_dict)
print()
#Using clear()
my_dict = {'a': 1, 'b': 2}
my_dict.clear()
print("Output for clear:")
print(my_dict)
print()
#Using copy()
my_dict = {'a': 1, 'b': 2}
new_dict = my_dict.copy()
print("Output for copy:")
print(new_dict)
