**To change the key in a dictionary in Python, you would need to create a new key-value pair in the dictionary using the new key and the value of the old key. Then, you can use the pop() method to remove the old key from the dictionary. To change the value of a key, you can simply reassign a new value to that key in the dictionary.**<\/p>\n

For example:<\/p>\n

“`python
\n# Create a sample dictionary
\nmy_dict = {‘a’: 1, ‘b’: 2, ‘c’: 3}<\/p>\n

# Change the key ‘a’ to ‘x’
\nmy_dict[‘x’] = my_dict.pop(‘a’)<\/p>\n

# Change the value of key ‘b’ to 10
\nmy_dict[‘b’] = 10<\/p>\n

print(my_dict)
\n“`<\/p>\n

This will output:<\/p>\n

“`
\n{‘b’: 10, ‘c’: 3, ‘x’: 1}
\n“`<\/p>\n

Changing keys and values in a dictionary can be useful when you need to update the data in a dictionary without creating a new dictionary from scratch.<\/p>\n
