Exercise # $1$:

Write a Python code that uses $4$ iterations. In each iteration, it selects a random letter from the alphabet.

If the selected letter is a vowel, it creates a substring from the alphabet starting from that vowel to then end.

If the selected letter is a consonant, it creates a substring starting from letter a to the selected consonant $($included$).$

Note: Use seed$(50)$ to compare your results with sample run.
