Instructions

Perform the tasks and answer the questions using Python code $($Jupyter notebook$).$ Display results when applicable. Take screenshots of your work and paste them.

To start performing each task, import the Numpy library and give it an appropriate alias name. Find the version of the Numpy package on your system.

Task $1$A

Julie scored $85$ in Mathematics, $65$ in English, $70$ in Social Science and $80$ in Science. Meanwhile, Tina scored $90$ in Mathematics, $60$ in English, $80$ in Social Science and $75$ in Science.

i$)$ Create two arrays to reflect Julie and Tina's scores respectively.

ii$)$ Create an array which holds $($boolean values$)$ i$.$e$.$ the comparison output of their scores. In how many subjects Julie scored more than Tina? Hint: Use the np$.$argwhere$()$ function.

Task $2$A

Create an array with the gems listed below. Make it a $3*2$ dimensional array.

Gems: ruby, diamond, emerald, jade, sapphire, garnet

i$)$ Print each element of the array using the nested $$for$$ loop. While printing, the $1$st letter of the gem has to be in capital letters.

ii$)$ Print each element of the array using a single $$for$$ loop. While printing, the $1$st letter of the gem has to be in capital letters.

Task $3$A

Create a two$-$dimensional array as $[[100,200,300],[400,500,600]].$

Convert it into a one$-$dimensional array and print it$.$

Divide the one$-$dimensional array by $100$ and print the new array. Ensure that the datatype of the new array is int$64.$

Task $4$A

Create an array with values $2,4,6$ and another array with $8,10,12.$

i$)$ Using the functions available in Numpy, create an array using the $2$ arrays above such that the result is:

$[[2,4,6],$

$[8,10,12]]$

ii$)$ Using the functions available in Numpy, create an array using the $2$ arrays above such that the result is:

$[[2,8],$

$[4,10],$

$[6,12]]$

Task $5$A

Create an array of numbers from $1$ to $50.$

Slice the array to create $3$ arrays $$

i$)$ The $1$st array contains numbers $1$ to $9.$

ii$)$ The $2$nd array contains numbers from $10$ to $20.$

iii$)$ The $3$rd array contains numbers from $21$ to $50.$
