how to access json object in python code example
Example 1: python read json file
import json
with open('path_to_file/person.json') as f:
data = json.load(f)
print(data)
Example 2: load json
import json
with open('data.txt') as json_file:
data = json.load(json_file)
Example 3: how to get specific data from json using python
with open('distros.json', 'r') as f:
distros_dict = json.load(f)
for distro in distros_dict:
print(distro['Name'])
Example 4: python import json data
# Basic syntax:
import ast
# Create function to import JSON-formatted data:
def import_json(filename):
for line in open(filename):
yield ast.literal_eval(line)
# Where ast.literal_eval allows you to safely evaluate the json data.
# See the following link for more on this:
# https://stackoverflow.com/questions/15197673/using-pythons-eval-vs-ast-literal-eval
# Import json data
data = list(import_json("/path/to/filename.json"))
# (Optional) convert json data to pandas dataframe:
dataframe = pd.DataFrame.from_dict(data)
# Where keys become column names
Example 5: read json data from file
fs.readFile(ROLES_FILE, "utf8", (err, data) => {
if (err) {
res.status(403).json({});
}
const [localScope, action] = scope.split(".");
const mapper = JSON.parse(data.toString("utf8").replace(/^\uFEFF/, ""));
const isAllowed = checkRole(mapper, localScope, action, role);
if (isAllowed) {
next();
} else {
res.status(403).json({});
}
