    I want to have Python 2.7 print out floating point numbers in scientific notation, forced to start with 0. For instance, assume

    >>> a = 1234567890e12
    >>> print '{:22.16E}'.format(a)
    1.2345678900000000E+21


    However, I want a print output that looks like:

    0.1234567890000000E+22


    Notice that the exponent is raised by one since the desired output is forced to a leading zero. How can I achieve this?
