import pymysql

# 查詢所有字段
def list_col(localhost, username, password, database, tabls_name):
    db = pymysql.connect(localhost, username, password, database, charset="utf8")
    cursor = db.cursor()
    cursor.execute("select * from %s" % tabls_name)
    col_name_list = [tuple[0] for tuple in cursor.description]
    db.close()
    return col_name_list

# 列出所有的表
def list_table(localhost, username, password, database):
    db = pymysql.connect(localhost, username, password, database, charset="utf8")
    cursor = db.cursor()
    cursor.execute("show tables")
    table_list = [tuple[0] for tuple in cursor.fetchall()]
    db.close()
    return table_list


username = "root" # 用戶名
password = "root" # 連接密碼
localhost = "localhost" # 連接地址
database = "school" # 數據庫名
tables = list_table(localhost, username, password, database) # 獲取所有表，返回的是一個可迭代對象
print(tables) 

for table in tables:
    col_names = list_col(localhost, username, password, database, table)
    print(col_names) # 輸出所有字段名
