Cannot connect to Mysql if @ in password

Question

I am having trouble connecting to the newer versions of mysql using PyMySQL==1.0.2 and SQLAlchemy==1.4.20 in python3.8. The reason is that pymysql reads @ symbol as a change form password to host:

schema_conn = sqlalchemy.create_engine(
    "mysql+pymysql://{user}:{password}@{host}/{db}"
    .format(host=config['host'], db=config['db'], user=config['user'],
    password=config['password']))

So that if my password is: bob@123 then pymysql reads it as password = bob and host = 123, and not bob@123 SO my question is how to I correctly replace @ as a text replace so that its read correctly. I tried the url version of @ which is %40 but that did not work. Thanks.
