Scientific notation in python

Question

Hi I know that to print a number in a scientific notation I can do the following

"%.3e" % 123.456

will give

1.234e+02

however how can I obtain

12.34e+01?

12.34e+01 is not scientific notation, what rules are you trying to accomplish when displaying numbers? — Tadhg McDonald-Jensen

For clarification, most usages of Scientific Notation refers to Normalized Notation which requires that the leading number be at least 1 but less than 10. In Engineering Notation, the exponent is a multiple of three. These are the two most commonly used versions of Scientific Notation.

Not precisely an answer, but too important a clarification to bury in the comments, so I guess it had better stay where it is.
