I don't know how to ask this, so I made up an example.
The goal is to compare the value of columns **A** & **B** to the values of *C*,*D* and *E* separately.
If the value is the same or higher (>=) then return '1' else '0'.

A B C D E 1 101 103 100 101 99 2 102 100 101 99 103 3 100 99 103 100 98

The desired outcome would be this:

A B C D E C D E 1 1 1 1 1 1 1 1 0 0 1 0 0 1 1 0 0 1

Ideally I would like a function for this, what's the best way to approach this?

Direct compare `A`

and `B`

to `C, D, E`

, and `concat`

them together

A = df[['C','D','E']].le(df[['A']].values).astype(int) B = df[['C','D','E']].le(df[['B']].values).astype(int) pd.concat([A,B], axis=1, keys=['A','B']) Out[650]: A B C D E C D E 1 1 1 1 1 1 1 2 1 1 0 0 1 0 3 0 1 1 0 0 1

**Excel: Compare two columns for matches and differences,** In the Duplicate Values dialog box, make sure 'Duplicate' is selected. Finding duplicate values in the same column is easy; you can sort or apply a filter depending on the circumstances. Finding duplicates that span multiple columns is a tad more difficult. A sort can

You can use with `le`

which checks for every column if its equal or less than `A`

and then `B`

:

cols = ['A', 'B'] compare = ['C', 'D', 'E'] for col in cols: print(col) df[compare].le(df[col], axis=0).astype(int)

**output**

A C D E 0 1 1 1 1 1 1 0 2 0 1 1 B C D E 0 1 1 1 1 0 1 0 2 0 0 1

It would be more elegant to make a dict with the column names as key:

cols = ['A', 'B'] compare = ['C', 'D', 'E'] dct = {col: df[compare].le(df[col], axis=0).astype(int) for col in cols} print(dct['A'], '\n') print(dct['B'])

**output**

C D E 0 1 1 1 1 1 1 0 2 0 1 1 C D E 0 1 1 1 1 0 1 0 2 0 0 1

**Compare Two Columns in Excel (for Matches & Differences ,** How do I do a Vlookup to compare two columns? To compare two columns in Excel row-by-row, write a usual IF formula that compares the first two cells. Enter the formula in some other column in the same row, and then copy it down to other cells by dragging the fill handle (a small square in the bottom-right corner of the selected cell). As you do this, the cursor changes to the plus sign:

How about broadcasting:

compares = df[['A','B']].values[:,:,None] >= df[['C','D','E']].values[:,None, :] compares = compares.reshape(len(df),-1) pd.DataFrame(compares, columns=pd.MultiIndex.from_product((list('AB'),list('CDE'))) ).astype(int)

Output:

A B C D E C D E 0 1 1 1 1 1 1 1 1 1 0 0 1 0 2 0 1 1 0 0 1

You could use pandas.DataFrame.apply

For example, in your case with `df`

being this dataframe

A B C D E 1 101 103 100 101 99 2 102 100 101 99 103 3 100 99 103 100 98

you could perform the following operation to compare A to C,D and E:

df[['C', 'D', 'E']].apply(lambda x: df['A'] >= x)

This will give you:

C D E True True True True True False False True True

With `True = 1`

and `False = 0`

. You could do the same to compare B to C,D and E. I hope this helps.
