Write a Python program to compute and print the following:

$1.$ The expected Southern Hemisphere average temperature in $2027$

$2.$ The expected increase after three years $($i$.$e$.$ in $2027)$ of the average temperature relative to $2024$

However, in this case, the average temperature in $2024$ and annual average temperature increase rates for $2025,2026,$ and $2027$ are provided as an input string as illustrated by the example input:

$12024=15\mathrm{.}9,2025=2\mathrm{.}2\%,2026-1\mathrm{.}5\%,2027-3\mathrm{.}1\%$

which specifies that the temperature for $2024$ is $15\mathrm{.}9,$ and the rates of increase of the average temperature for $2025,2026$ and $2027$ are $2\mathrm{.}2\%,1\mathrm{.}5\%$ and $3\mathrm{.}1\%$ respectively.

The expected input$/$output behavior of the program is illustrated below for two example inputs:

Enter input string: $2024=13\mathrm{.}2,$ r$2025=1\mathrm{.}2\%,2026=1\mathrm{.}7\%,2027=2\mathrm{.}1\%$

Expected Average Temperature for $2027$: $13\mathrm{.}87$

Total increase by $2027$ relative to $2024$: $0\mathrm{.}67$

Enter input string: t$2024=15\mathrm{.}9,2025=2\mathrm{.}2\%,2026=1\mathrm{.}5\%,$

r$2027=3\mathrm{.}1\%$

Expected Average Temperature for $2027$: $17\mathrm{.}0$

Total increase by $2027$ relative to $2024$: $1\mathrm{.}1$

PLEASE WRITE CODE IN PYTHON AND SHOW THE CODE WITH EXPLANATION, THANK YOU!
