Creating a new column based on the values of other columns

Question

I wanted to create a \"High Value Indicator\" column, which says \"Y\" or \"N\" based on two different value columns. I want the new column to have a \"Y\" when Value_1 is >

Answer 1

Using map

df['High Value Indicator'] =((df.Value_1 > 1000) | (df.Value_2 > 15000)).map({True:'Y',False:'N'})
df
Out[849]: 
   ID  Value_1  Value_2 High Value Indicator
0   1      100     2500                    N
1   2      250     6250                    N
2   3      625    15625                    Y
3   4     1500    37500                    Y
4   5     3750    93750                    Y
