以下は、PythonでJSONデータを動的にデシリアライズするためにjsonモジュールを使用する方法の例です：

```
import json

# Load the JSON data into a variable
json_data = '{"name": "John Doe", "age": 34}'

# Deserialize the JSON data into a Python object
data = json.loads(json_data)

# Access the data
print(data['name']) # prints "John Doe"
print(data['age'])  # prints 34
```
Below is an example of how to use the json module to dynamically deserialize JSON data in Python:

import json

# Load the JSON data into a variable
json_data = '{"name": "John Doe", "age": 34}'

# Deserialize the JSON data into a Python object
data = json.loads(json_data)

# Access the data
print(data['name']) # prints "John Doe"
print(data['age'])  # prints 34
