Lucky numbers in Python

I wrote a function lucky_numbers: def lucky_numbers(n): if n < 3: return [1] sieve = range(1, n + 1, 2) sieve_index = 1 while True: skip_count = sieve[sieve_index] sieve_len = len(sieve) if sieve_len < skip_count

How to print zero-padded floating point numbers in python 2.6.1

Hello, I thought that I could zero-pad a floating point number in 'print' by inserting a zero after '%', but this does not work. I get: print '%2.2F' % 3.5 3.50 print '%02.2F' % 3.5 3.50 How can I get print (in a simple way) to print 03.50? Best Regards, Lorenzo -- http://mail.python.org/mail

If your still worried by using floats for your values you may wish to look into the decimal module: http://docs.python.org/lib/module-decimal.html Example: >>> from decimal import Decimal >>> Decimal(2) + Decimal('1.47') Decimal("3.47") Regards, Neil -- http://mail.python.org/mailman/listinf
