从 Flask 导入Flask import Flask , render_template
import  os  # 导入操作系统模块
import  pymongo
 
MONGODB_URI = 'mongodb+srv://asabeneh:your_password_goes_here@30daysofpython-twxkr.mongodb.net/test?retryWrites=true&w=majority'
client = pymongo.MongoClient(MONGODB_URI)
db = client['thirty_days_of_python'] # accessing the database
 
query = {'name':'John'}
db.students.delete_one(query)
 
for student in db.students.find():
    print(student)
# lets check the result if the age is modified
for student in db.students.find():
    print(student)
 
 
app = Flask(__name__)
if __name__ == '__main__':
    # for deployment we use the environ
    # to make it work for both production and development
    port = int(os.environ.get("PORT", 5000))
    app.run(debug=True, host='0.0.0.0', port=port)
