Data I have
ID C1 C2
1 A B
4 B A
What needed (Step 2):
***Most importantly the original data coming could have multiple C columns, we need to fetch them. today we have C1 & C2, tomorrow we could have C1 to C10.The excel data they dump could have multiple c columns.
the python code should know how many C columns came up in the dataset, dynamically build step 2.
the python code only knows the excel filename.
