Hellooo

I want to create a new column (D) that includes calculations from previous columns (A,B,C).

How could I do that?

CodePudding user response：

You can use assign() method in Pandas to create a new column D.

Example:

df = df.assign(D=df["A"]   df["B"]   df["C"])

CodePudding user response：

Just do so directly

df["D"] = df["A"]   df["B"]   df["C"]
