'how to convert integer to exponential in different forms for the same value in python

I am trying to get exponential value in different form for the same value. for example:

print('{:e}'.format(100))

ans=1.000000e+02. this is working fine

I want answer like,

ans1: 0.10000e+03

ans2: 0.01000e+04

ans3: 10000.00000e-2

how to achieve these?
