Can someone who is experienced in python, please do the following (anything general nothing in particular)?

Create a coding program that looks at how bacteria grows over time with bacteria by doubling :

1) Has a custom function which is called numerous times, at least once by inputs that you hard-code into the program and once with some user-submitted inputs

2) Plots something, with the graph partially customized.

Thanks in advance and I will be sure to leave a like! This is more of a general request since I would just like to see an example!
