Unnecessary use of json.loads() for file data PY-W0078
Anti-pattern
Major
Autofix The json module provides two ways to read JSON data: a .loads() method that
accepts a JSON string, and a .load() method, that works on files directly.
So instead of reading a file manually and passing it to json.loads(), it is
recommended to use json.load() directly.
Bad practice
with open('data.json') as file:
data = json.loads(file.read()) # Reading file manually
class Socket:
def read_json(self, data):
json.loads(self.socket.read()) # Reading socket manually
self.socket.close()
Recommended
with open('data.json') as file:
data = json.load(file) # Directly passing the file object
class Socket:
def read_json(self, data):
json.load(self.socket) # Directly passing the socket object
self.socket.close()
