Help sending SMS with a variable in body of message

So I am using the code below to text me the price of a stock ticker symbol. The texting SMS message piece works fine. I also get the ticker symbol to output to the screen but I can not figure out how to add the variable to the body= section of code. If you notice I am trying to add the value of ‘market_price’ to the body of the text message. Can someone tell me what is missing? Thank you!

import os
from import Client
import yfinance as yf

ticker = yf.Ticker('NLST').info
market_price = ticker['regularMarketPrice']
previous_close_price = ticker['regularMarketPreviousClose']
print('Ticker: NLST')
print('Market Price:', market_price)
print('Previous Close Price:', previous_close_price)

account_sid = os.environ['TWILIO_ACCOUNT']
auth_token = os.environ['TWILIO_AUTH_TOKEN']
client = Client(account_sid, auth_token)
message = client.messages \
                     body="Nestlist stock price is {'market_price'}",

You must put a f at the start of an string that {} is used for replacement.
Also you do not need quotes around market_price.

Here are examples:

:>>> market_price='$19.61'
:>>> print('The mark price {market_price}')
The mark price {market_price}
:>>> print(f'The mark price {market_price}')
The mark price $19.61
:>>> print(f"The mark price {'market_price'}")
The mark price market_price

Does the create() method know what to replace the + with in the phone number?

thank you! Yes this worked → ```
:>>> print(f’The mark price {market_price}')
