Use Pandas to_sql (https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_sql.html). This should work for you:

import mymysql
from sqlalchemy import create_engine
sql_table_name = 'country2'
engine = create_engine("mysql://testuser:test123@localhost:0/world") # creat engine
df1.to_sql(sql_table_name, engine) # add to table
