Does python suck or I am just stupid?

To avoid accumulation of small rounding errors while
successive adding of small float values in loops
it's preferable to write something like
 u = i * u_inc
 i += 1
instead of
 u = u + u_inc

This will make your problem disappear so you can
stop head banging :)
