Day 335: Python controlling the System (Subprocess) 🔧 Running Shell Commands from Python Sometimes Python isn't enough. Sometimes you need to run a git command, ping a server, or execute a C++ program from your Python script. The subprocess module is the bridge between Python and your Operating System. import subprocess # Running a simple echo command # capture_output=True lets us store the result in a variable result = subprocess.run(['echo', 'Hello from the shell!'], capture_output=True, text=True) print(f"Shell said: {result.stdout}") My Use Case: I recently used this to automate a git backup script that runs git add and git commit automatically at the end of the day. #Automation #SystemAdmin #Python #DevOps

The 4 Core JSON Functions in Python - When to Use What? If you work with JSON in Python, these four functions are all you need. But knowing when to use which is key: 📌 Common Scenarios: I have bytes from Pub/Sub → json.loads(message_bytes.decode("utf-8")) I have a JSON string → json.loads(json_string) I have a dict and want a string → json.dumps(my_dict) I have a dict and want bytes → json.dumps(my_dict).encode("utf-8") I want to parse from a file/stream → json.load(file) I want to write JSON to a file/stream → json.dump(obj, file) 💡 Pro Tip: load/dump → for files or streams loads/dumps → for strings in memory #Python
