使用pymongo

pip install pymongo

更新元素的示例代码：

from pymongo import MongoClient

# Connect to the MongoDB database server (change 'localhost' and '27017' as necessary)
client = MongoClient('mongodb://localhost:27017/')

# Connect to the specific database and collection
db = client['your_database_name']  # Replace 'your_database_name' with the name of your database
collection = db['Queue']

# Query to find the document
query = {"dr-name": "1guna", "queue.2.0": "3"}

# Update statement to change the status
update = {"$set": {"queue.2.3": "Done"}}

# Perform the update
result = collection.update_one(query, update)

# Output the result of the update
print("Documents updated:", result.modified_count)

# Close the connection
client.close()
