Print number in engineering format

Question

I am trying to print a number into engineering format with python, but I cannot seem to get it to work. The syntax SEEMS simple enough, but it just doesn\'t work.

Answer 1

It is 2020 now folks! and there is an COVID-19 pandemic. You got to use f-string literals for this type of work:

With python3.6.4 and above, you can do

a = 3e-4
print(f"{a:.0E}")
