This is my code in python I keep getting these errors that do not match the expected output, I confused on what I did wrong how do I correct this.

# Bull Kelp and Purple Urchin Population Simulator ## Model Parameters This simulator models the interaction between Bull Kelp and Purple Urchin populations. Users input growth and death rates for each species. Rates must be non-negative. ### Kelp Parameters: - **Growth Rate (`a`)**: The rate at which the kelp population grows. - **Death Rate (`b`)**: The rate at which kelp dies. **Error Handling**: Negative input for rates results in an error message and exits the program. ### Urchin Parameters: - **Birth Rate (`c`)**: The rate for urchin population increase. - **Death Rate (`d`)**: The rate of urchin mortality. **Error Handling**: Similar checks and errors apply to urchin rates. ### Initial Population - Users set initial populations for kelp and urchins (in thousands). ### Simulation - **Timescale**: Users input the duration for the simulation. Negative timescales trigger an error. #### Computation: - Uses a loop over the timescale to calculate changes in populations. - Updates kelp (`k`) and urchin (`u`) populations each iteration. - Calculates minimum, maximum, and total populations for kelp and urchins. ### Results: - The output includes average populations for kelp and urchins, as well as minimum and maximum populations recorded during the simulation. This simulator allows exploration of ecological interactions, promising insights into population dynamics through customizable parameters and initial conditions.

Expert Solution
Step 1: Errors in the program

There are extra printing statements in the original code. Therefore, the expected output does not match your output.

If any other statement doesn't match, kindly remove any extra print statement.
