I am learning Python now. It is too complicated. I started the file that i did but it crashed. Can you show me how to do it?

Write a Python program to convert a given weight from kg to pound and to gal and to liter.

1kg=0.2642gal=2.205lb

1gal = 3.785liter

It means when i open the file using python. I just put a number and hit enter. I will get something like:

123kg=.....lb=....gal=....l

Thank you
