5. What will be the output produced on the execution of the following code?
import string
startString = '#NaTO5*'
finalString = ' '
pos = 0
value = 1
while pos < len(startString):
if startString[pos] >= '0' and startString[pos] <= '9':
value = int(startString[pos])
value = value - 1
finalString = finalString+startString[value]
elif startString[pos].isupper():
if startString[pos] not in 'AEIOU':
finalString = finalString + '$'
else:
finalString = finalString + startString[pos + 1]
else:
finalString = finalString + '*'
pos = pos + 1
print(finalString)
Ans. *$*$5O*

6. Consider the following string:

(v) quote.isupper()
(vi) quote.islower()
(vii) quote.isalpha()
