Answer 1

LINE 4: while x < len(sample_string):
This is the start of the while loop that runs as long as x is less the length of input string.

LINE 5: if sample_string[x].lower() not in 'aeiou' and sample_string[x].isalpha():
This is the conditional statement inside the while loop. It checks every character of input string in lowercase if it's not a vowel( not in 'aeiou') and if it's an alphabetic character(isalpha).
If both conditions are true, it increments the counter by 1.
