### Install ThreadSafe JSON Dict with pip

Source: https://github.com/rato-tokyo/threadsafe-json-dict/blob/main/README.md

This snippet shows how to install the `threadsafe-json-dict` library using pip. It's a simple command to get the package ready for use in your Python projects.

```bash
pip install threadsafe-json-dict
```

--------------------------------

### Basic Usage of Python ThreadSafeJsonDict

Source: https://github.com/rato-tokyo/threadsafe-json-dict/blob/main/README.md

Demonstrates fundamental operations of `ThreadSafeJsonDict`, including creating an instance, setting and retrieving data like a standard Python dictionary, saving data to a JSON file, and closing the resource. Remember to specify a directory for diskcache's internal files.

```python
from threadsafe_json_dict import ThreadSafeJsonDict

# Create a dictionary (specify the directory for diskcache's internal files)
data = ThreadSafeJsonDict("my_data_cache")

# Dictionary-like operations
data["user_info"] = {
    "name": "Alice",
    "age": 30,
    "email": "alice@example.com"
}
data["settings"] = {
    "theme": "dark",
    "notifications": True,
    "language": "ja"
}

# Read data
print(data["user_info"])  # {'name': 'Alice', 'age': 30, 'email': 'alice@example.com'}
print(len(data))          # 2

# Save in JSON format
data.save("output/data.json")

# Clean up resources
data.close()
```

--------------------------------

### Load JSON Data into Python ThreadSafeJsonDict

Source: https://github.com/rato-tokyo/threadsafe-json-dict/blob/main/README.md

Shows how to initialize `ThreadSafeJsonDict` by loading data from an existing JSON file. The `load()` method populates the dictionary with the contents of the specified file, allowing for easy data persistence and retrieval.

```python
from threadsafe_json_dict import ThreadSafeJsonDict

# Load from an existing JSON file
data = ThreadSafeJsonDict("loaded_data_cache")
data.load("input.json")

# Verify data
for key, value in data.items():
    print(f"{key}: {value}")

data.close()
```

--------------------------------

### Manage ThreadSafeJsonDict with Python Context Manager

Source: https://github.com/rato-tokyo/threadsafe-json-dict/blob/main/README.md

Illustrates using `ThreadSafeJsonDict` as a context manager with a `with` statement. This ensures proper resource cleanup (e.g., closing the underlying diskcache) automatically upon exiting the block, simplifying resource management.

```python
from threadsafe_json_dict import ThreadSafeJsonDict

with ThreadSafeJsonDict("my_data_cache") as data:
    data["key1"] = "value1"
    data["key2"] = {"nested": "data"}
    data.save("output.json")
# Resources are automatically cleaned up
```

--------------------------------

### Implement Thread-Safe Concurrency with Python ThreadSafeJsonDict

Source: https://github.com/rato-tokyo/threadsafe-json-dict/blob/main/README.md

Demonstrates the thread-safe capabilities of `ThreadSafeJsonDict` by showing concurrent access from multiple threads. Each thread adds items and saves its own JSON output, highlighting the class's ability to handle parallel operations safely.

```python
import threading
from threadsafe_json_dict import ThreadSafeJsonDict

data = ThreadSafeJsonDict("concurrent_data_cache")

def worker_thread(thread_id):
    for i in range(10):
        data[f"thread_{thread_id}_item_{i}"] = f"value_{i}"
        
    # Thread-safe saving
    data.save(f"thread_{thread_id}_output.json")

# Execute concurrently with
```
