6. How do you handle nested data in a string while converting to a list? Use json.loads() to parse structured JSON data into nested lists. Here’s an example: import json string = '{"apple": ["red", "green"], "banana": ["yellow", "green"]}' nested_list = json.loads(string...
We specify the format string as the second argument to strptime(), including the %z formatting code to parse the timezone offset. While the function we saw above may seem easy in theory, it can also be a source of frustration when things go wrong in practice. Troubleshooting Common ...
To parse a JSON data string to a Python object, use the json.loads() method of the built-in package named json. The json.loads() method parses the provided JSON data string and returns a Python dictionary containing all the data from the JSON. You can get parsed data from this Python...
Since the function has no statements in its block, Python can’t parse this code. Once again, pass can help you: Python def write_to_file(fname, data): # Discard data for now # with open(fname, "w") as fpout: # fpout.write(data) pass get_data(source).add_callback(write_to...
