Hi, I'm looking for some lines of code that does the following: I have a dataframe with 160 Columns and a number of rows (max 30):
Col1 Col2 Col3 ... Col 159 Col 160 Row 1 0 0 LD ... 0 VD Row 2 HD 0 0 0 MD Row 3 0 HD HD 0 LD Row 4 LD HD HD 0 LD ... ... LastRow HD HD LD 0 MD Now I want a dataframe that looks like this. As you see all duplicates are removed. Can this dataframe be constructed in a fast way? Col1 Col2 Col3 ... Col 159 Col 160 Row 1 0 0 LD 0 VD Row 2 HD HD 0 0 MD Row 3 LD 0 HD 0 LD Thx for helping me out.
