我有两个数据帧;
df1 as;
Name Role
Jim Accounts
Sam Purchase
Rhea Sales
df2 as;
Name Date
Jim 1/1/2000
Jim 2/1/2000
Jim 3/1/2000
Sam 1/1/2000
Sam 2/1/2000
Rhea 1/1/2000
Rhea 2/1/2000
我想查找df1并将输出设为;
Name Date Role
Jim 1/1/2000 Accounts
Jim 2/1/2000 Accounts
Jim 3/1/2000 Accounts
Sam 1/1/2000 Purchase
Sam 2/1/2000 Purchase
Rhea 1/1/2000 Sales
Rhea 2/1/2000 Sales
我无法弄清楚Pandas的查找功能。
