Code shows results when run interactively, but not when run from a shell

Question

I borrowed this little scientific notation script from another poster: Display a decimal in scientific notation.

def format_e(n):
    a = \'%E\' % n
    return a         


        

Answer 1

The interactive interpreter auto-echoes the results of any expression that doesn't return None. In a script you need to explicitly print the results you want to see:

print format_e(Decimal('40800000000.00000000000000'))
print format_e(Decimal('40000000000.00000000000000'))
print format_e(Decimal('40812300000.00000000000000'))
