Is there any way to generate random numbers based on arbitrary real valued

log and exponential functions.

scipy[1] has a large collection of "standard" univariate pdfs, including

normal, exponential, gamma, and the like.

One cannot generate random numbers from arbitrary real valued functions

because a function needs to satisfy certain restrictions to be a pdf.

For example, you cannot generate random numbers "with a log function",

unless you restrict the domain and renormalize.

Generating random numbers from an arbitrary pdf is possible, but tricky.

I encourage you to search the literature for "monte carlo sampling."
