Introduction
Writing to a JSON file
Instruction
Great! First, we'll learn how to convert a Python object into a JSON string.
Take a Python object like this:
data = {
'first_name': 'Guido',
'second_name': 'van Rossum',
'titles': ['BDFL', 'Developer']
}
You can use the json.dumps() function to produce a string representing a JSON object. The name of the function means dump the data as a string, note that the final "s" in "dumps" stands for "string". The function requires an argument denoting the object you'd like to dump:
json.dumps(data)
Finally, we can print the result:
print(json.dumps(data))
Exercise
We have saved some information in a Python object named data. Using json.dumps(), convert this object to a string and print the result. Is the output readable?
