What am I supposed to do with challenges? I am stuck between first and second test: when I print the first solution, second test fails and vice versa. Give me a hint, please

Just the first one about column. I print(col[:,0] and have the right result for the first test but it doesn't match with second. Then I add a line of code but with the right solution for the second I get the error from the first one.
