python连接数据库：

import pymysql
创建connectinon对象：
con = pymysql.connect(host = "localhost",user = "root",password = "123",db = "day32",charset = "utf8")
创建cursor对象：
car = con.cursor()
car.execute("select * from sanguo")
data = car.fetchall()
print(data)
for i in data:
    print(i)

//对数据库表中插入数据操作：
import pymysql
conn = pymysql.connect(host = "localhost",user = "root",password = "123",db = "day32",charset = "utf8")
cur = conn.cursor()
cur.execute('insert into sanguo1 values(4,"孙权")')
conn.commit()

//用户交互连接数据库操作：
import pymysql
conn = pymysql.connect(host = "localhost",user = "root",password = "123",db = "day32",charset = "utf8")
cur = conn.cursor()
id = input("请输入ID号：")
name = input("请输入名字：")
cur.execute('insert into sanguo1 values(%d,"%s")' %(int(id),name))
conn.commit()

//封装连接数据库：
import pymysql
cur = None
conn = None
def getall(sql):
    conn = pymysql.connect(host = "localhost",user = "root",password = "123",db = "day32",charset = "utf8")
    cur = conn.cursor()
    cur.execute(sql)
    return cur.fetchall()
def exceDML(sql):
    conn = pymysql.connect(host = "localhost",user = "root",password = "123",db = "day32",charset = "utf8")
    cur = conn.cursor()
    cur.execute(sql)
    conn.commit()
def close():
    if cur:
        cur.close()
    if conn:
        conn.close()

//模拟mp3存储音乐的路径和歌曲名：
import pymysql
conn = pymysql.connect(host = "localhost",user = "root",password = "123",db = "music",charset = "utf8")
cur = conn.cursor()
name = input("输入歌曲名：")
mpath = input("输入音乐下载路径：")
cur.execute('insert into music values("%s","%s")' %(name,mpath))
conn.commit()

#//项目实现要求：
# 可以通过Python向数据库中添加歌曲名和所在路径（可以手动输入，模拟歌曲下载）
# 通过Python从数据库中取得想听的歌曲名，歌曲路径，用得到的路径进行音乐播放（注意格式），并print打印当前正在播放的歌曲名（不要求连续播放）
# 尝试把项目中的常用功能封装成模块
import pygame
import time
import pymysql
con = pymysql.connect(host = "localhost",user = "root",password = "123",db = "day33",charset = "utf8")
car = con.cursor()
name = input("请输入歌名：")
path = input("请输入路径：")
# 十年
# E:\韩红 - 十年(Live).mp3
car.execute("insert into t_music1 values(13,%s,%s)",(name,path))
con.commit()
car.execute("select * from t_music1")
data = car.fetchall()
print(data)
data = data[-1][-1].replace("\\","\")
print(data)
pygame.mixer.init()
pygame.mixer.music.load(data)
pygame.mixer.music.play()
time.sleep(100)

python听歌：

import pygame
import time
pygame.mixer.init()
pygame.mixer.music.load(f"F:无损音乐洛天依 - 洛天依投食歌.mp3")
pygame.mixer.music.play()
time.sleep(100)
结果：  pygame 1.9.6
