仮想マシンの構築方法

以下のVagrantfileで、Jupyter LabとMariaDBをインストールした仮想マシンを構築できます。

○動作確認用コード(MariaDB接続確認)

import MySQLdb

con = MySQLdb.connect(
  user='test',
  passwd='test',
  host='localhost',
  db='test')

try:
  cur= con.cursor()
  sql = "select message_id, message from messages"
  cur.execute(sql)

  for row in cur.fetchall():
    print(row)

except MySQLdb.Error as er:
    print('MySQLdb.Error:', er)
cur.close
con.close

〇動作確認用コード(folium動作確認)

import folium

fm = folium.Map(location=[35.856999, 139.648849], zoom_start=10)

folium.Marker(location=[35.861729,139.645482], popup='さいたま市').add_to(fm)
folium.Marker(location=[35.975198, 139.752301], popup='春日部市').add_to(fm)
    
fm
