QUESTION
I have two frames. df1
containing thousands of rows of four columns of string data. The string data can be almost anything but what matters is which columns match. Here I just chose character names for illustration. Within one row of df1
, the four columns when compared, are a code for 1 of 14 fairly complex equations. df2
contains the code and pre-calculated results for the 14 equations. Instead of calculating each of the thousands of values on the fly, I want to compare the four columns in df1
and populate a Result
column using the pre-calculated results from df2
.
df1
looks like this:
ANSWER
Answered 2020-Sep-23 at 17:35Here's an idea:
- Find out the number of unique representations across df1 referring to this. For example, you get 5 unique values 'A', 'B', 'C', 'D', and 'E' across all columns.
- Make a new column at df1 and assign the 'code' for the four columns. For example, df1[0, code'] = 'AAAA'.
- Join the column 'code' at df1 with the column 'code' at df2. You'll get the 'result' column at df1.
