# Basic syntax:
# Approach 1:
dictionary[new_key] = dictionary[old_key]
del dictionary[old_key]
# Approach 2:
dictionary[new_key] = dictionary.pop(old_key)
my_dict = {
'foo': 42,
'bar': 12.5
}
my_dict['foo'] = "Hello"
print(my_dict['foo'])
#This will give the output:
'Hello'
python = {
"year released": 2001,
"creater":"Guido Van Rossum"
}
print(python)
python["year released"] = 1991
print(python)
dictionary["key"] = newvalue
d = {1: "one", 2: "three"}
d1 = {2: "two"}
# updates the value of key 2
d.update(d1)
#Output
{1: 'one', 2: 'two'}
