我有两个数据帧，df1是
ID Work WorkID TechnicianID
10112 Teacher W001 1332
10112 Teacher W001 1332
10112 Teacher W001 1334
10113 Artist W002 1335
10113 Artist W002 1336
10113 Artist W002 1336
10113 Artist W002 1337
df2，
TechnicianID Rating
1332 3.3
1334 4.1
1335 2.4
1336 4.3
1337 3.7
我希望最终的数据集同时加入两个数据框，
ID Work WorkID TechnicianID Rating
10112 Teacher W001 1332 3.3
10112 Teacher W001 1332 3.3
10112 Teacher W001 1334 4.1
10113 Artist W002 1335 2.4
10113 Artist W002 1336 4.3
10113 Artist W002 1336 4.3
10113 Artist W002 1337 3.7
有人可以帮我弄清楚该怎么做吗？
