Re: [Tutor] sales tax

As Michael points out, you need to explicitly use the round function, as the float formatting merely truncates anything after the second decimal place. I ran across a similar problem with the int() fuction early on. Anything after the decimal point is truncated, not rounded, leading to behavior I

Hi, You should look at the 'csv' module in the Python Standard Library. If you export your excel data to csv format, you can easily import the data in to python using the csv module. Ian On 9/6/07, saradhi dinavahi <[EMAIL PROTECTED]> wrote: > > hello all, > > I am new to the Python Programming.

Hi Max, A better way to check if a number is odd or even would be to find the remainder after it is divided by two. for instance: 4 divided by 2 = 2 with 0 remainder 5 divided by 2 = 2 with 1 remainder 6 divided by 2 = 3 with 0 remainder 7
