Display a decimal in scientific notation
from decimal import Decimal ‘%.2E’ % Decimal(‘40800000000.00000000000000’) # returns ‘4.08E+10′ In your ‘40800000000.00000000000000’ there are many more significant zeros that have the same meaning as any other digit. That’s why you have to tell explicitly where you want to stop. If you want to remove all trailing zeros automatically, you can try: def format_e(n): a=”%E” … Read more
Output in a table format in Java’s System.out
Use System.out.format . You can set lengths of fields like this: System.out.format(“%32s%10d%16s”, string1, int1, string2); This pads string1, int1, and string2 to 32, 10, and 16 characters, respectively. See the Javadocs for java.util.Formatter for more information on the syntax (System.out.format uses a Formatter internally).
