Can I restart the function from a specific step in python?

Question

crossing_river()

Doing a small text-based game....There are situations depend on user's input

What I want to do is that if user put unsuitable data, repeat the function starting from the checking if statement(mentioned with >>>> above) not from the beginning of the function

Is it possible???

I have done nested functions but it failed......also I tried to make a separated checking function ,but the code will become unclean
