Pandas alter columns based on condition

I have data set like this:

                 Team  First Season  Sec Season  Third Season  Total Games  0      Dallas Cowboys          1960     222          1245           694  1       Chicago Bears          1920     456          1665           657  2   Green Bay Packers          1921     1123          876           1339  3      Miami Dolphins          1966     1456          445           792  4    Baltimore Ravens            12     1123          232           326  5  San Franciso 49ers          1950     332           123           1003  

I want to make column for first/sec and third season as 0 if total games < 700.

This is what I am doing:

col = ['First Season', 'Sec Season', 'Third Season']  df[df['Total Games']<700, col] = 0.0  

This throws error why?
