$1.$ Your code will read the names of several animals $($maximum $20)$ from a given file named

animals.txt

$2.$ Upon successfully reading the file, your code will generate another file to be written to disk. For each animal listed in animals.txt you will generate a number of such animals as residents of the simulated zoo. You will name the file, residents.txt$.$

$3.$ There must be one or more residents of the same animal type. For example, if you read Tiger from animals.txt$,$ you must create multiple instances of Tiger and identify each one by a $5-$letter nickname generated randomly. The first letter of the nickname must be capitalised and the second letter cannot be the same as the first letter. Limit the number of instances of an animal to no more than $4$ because you need to be mindful of the cost of feeding them. The number of instances must be generated randomly.

$4.$ For each identifiable resident animal, you must assign an age chosen randomly between $1$ and $20($inclusive$)$ years.

$5.$ For each identifiable resident animal, you must assign an initial weight chosen randomly between $2\mathrm{.}5$ kg and $30\mathrm{.}5$ kg $($inclusive$).$

$6.$ For each identifiable resident animal, you must assign a gender chosen randomly as either female or male.
