float formatting

[Brian]

Hello all,

I am a bit stuck with a float formatting issue.  What I want to do is
print a float to the screen with each line showing one more decimal
place.  Here is a code snip that may explain it better:

#!/usr/bin/env python

num1 = 32
num2 = 42.98765

for i in range(2,7):
	print "|" + "%10.3f" % num2 + "|"

In the for loop, is the line with my difficulty.  In a perfect world it
would read something like this:

for i in range(2,7):
    print "|" + "%10.if" % num2 + "|"  #where i would be the iteration
and the num of decimal places

However, if I do that I get errors saying that all args were not
converted during string formatting.  An escaped 'i' does not work
either.

Any thoughts would be appreciated.

Thanks,
Brian
