I have a very old piece of software in my lab that only takes input in a format as
product1, test1, test2, test3
product2, test1, test4
so the software knows to apply test1/2/3 on product 1 and test1/4 on product2.
Now I have collected much new information in a long format like:
import pandas as pd
D = pd.DataFrame({
'Product':['A', 'A', 'A', 'B', 'B'],
'Test': ['t1', 't2', 't3', 't3', 't4'],
})
print(D)
Product Test
0 A t1
1 A t2
2 A t3
3 B t3
4 B t4
Is there any way to convert the table to
A, t1, t2, t3
B, t3, t4
It does not really have to a dataframe. Some plain text is pretty OK to copy and paste already.
