"%.3e" % 123.456

however how can I obtain

12.34e+01?

Answer 1

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.
