Pandas: Map DF with multiple columns to another

I am trying to figure out an efficient way to map df2 to df1. What makes this a bit trickier, is the key can sometimes be a tuple of 2+ keys.

df1 = {'Index':[1,2,3,4,5,6,7,8],'key':[a,a,b,(a,c),c,(a,b,c),b,a]}

df2 = {'Index':[a,b,c],'Val1':[1,2,3],'Val2':[.1,.2,.3],'Val3':[10,20,30],'Val4':[1,2,3],'Val5':[2,4,6]}

Basically, I am trying to map df2 (via the Index) to the key in df1. The end result would have columns = [key, Val1, Val2, Val3, Val4, Val5], and in the result that the type(key) == tuple, I would like a tuple of the 2+ matched Vals.

Any help is appreciated! Thanks!

Prop `className` did not match in next js app

I have written a sample code ( Github Link here ). this is a simple next js app, but giving me error when I refresh the page. This seems to be the common problem and I tried the fix provided in the internet but does not seem to fix my issue. The error is Warning: Prop className did not match. Server: "MuiBox-root MuiBox-root-1" Client: "MuiBox-root MuiBox-root-2".

Could someone take a look and help me whats wrong with the code? Via Active questions tagged javascript - Stack Overflow https://ift.tt/2FdjaAW
