import pymysql

#连接mysql数据库
IP = "192.168.50.7"
Port= 3306
UserName ="root"
Password="*******"
DbName ="world"
conn = pymysql.connect(host=IP, user=UserName,password=Password,database=DbName,charset="utf8")
# 定义执行SQL语句对象
cursor = conn.cursor()
# 定义执行SQL语句
sql ="select * from  city;"

# 执行SQL语句
cursor.execute(sql)
# 获取所有记录列表
results = cursor.fetchall()
#根据表字段定义变量
for row in results:
    ID = row[0]
    Name = row[1]
    CountryCode = row[2]
    District = row[3]
    Population = row[4]
    # 打印结果
    print("ID=%s,Name=%s,CountryCode=%s,District=%s,Population=%s" % \
          (ID, Name, CountryCode, District, Population))



# 关闭光标对象
cursor.close()
# 关闭数据库连接
conn.close()
