write me script that shows the saves a dictionnary in json format in a file in python

Here is a script that demonstr ates how to save a dictionary in JSON format to a file in Python : \n ``` \n import json \n \n # Create a dictionary \n my _ dict = {' key 1 ': ' value 1 ', ' key 2 ': ' value 2 ', ' key 3 ': ' value 3 '} \n \n # Save the dictionary to a file in JSON format \n with open (' my _ dict . json ', ' w ') as f : \n json . dump ( my _ dict , f ) \n ``` \n This script creates a dictionary called ` my _ dict ` with three key - value pairs . It then uses the ` json . dump ()` function to write the dictionary to a file called ` my _ dict . json ` in JSON format . The ` w ` mode spec ifies that the file should be opened for writing , and the ` json . dump ()` function writes the dictionary to the file . \n \n You can also use the ` json . d umps ()` function to convert a dictionary to a JSON string , and then write the string to a file using the ` json . dump ()` function . Here is an example : \n ``` \n import json \n \n # Create a dictionary \n my _ dict = {' key 1 ': ' value 1 ', ' key 2 ': ' value 2 ', ' key 3 ': ' value 3 '} \n \n # Convert the dictionary to a JSON string \n json _ str = json . d umps ( my _ dict ) \n \n # Save the JSON string to a file \n with open (' my _ dict . json ', ' w ') as f : \n f . write ( json _ str ) \n ``` \n This script is equivalent to the first script , but it uses the ` json . d umps ()` function to convert the dictionary to a JSON string before writing it to the file . </s>
