What is the truth value of 0 and 1? print 'True' if 0 else 'False' print 'True' if 1 else 'False' So what is the outcome of the following? result = 2 % 2 print result, not result if not result: print 'Even' if result: print 'odd' > > Another question. > > How can I round outcome of a calculation. > > round ( ( t-32)/1.8) does not work because I get a message that there are > two arguments. > > Outcome = (t-32)/1.8 > outcome2 = round (outcome) does not work because the argument must be a > string or a number > What is the type of t? In [39]: t = 3 In [40]: round((t-32)/1.8) Out[40]: -16.0 In [41]: t = 3.0 In [42]: round((t-32)/1.8) Out[42]: -16.0 Works fine for me. HTH, Wayne
