Lab 1

Q1. Write a Python program with the following function building block.

•All input values are to be taken fro

m the user.
•Ensure to check for possible error cases like mismatch of data type and input out of range,
for every function.

      Function 1:

countVowels(sentence) – Function that returns the count of vowels in a sentence.

Function 2:

Sum of all even numbers between two numbers, identify number of parameters  

Q2. Write a Python program that reads a text file called “perfumes.txt”. A sample of the file is provided below, you may add more details to the file. Each row has a perfume name and respective price. Your program must read the data from the file and identify the most expensive perfume in the list. Sample file is given below.

Gucci 415
Prada 435
Cartier 310
Hermes 553
Dior 386
Burberry 369

Answer 1

def countVowels(sentence): count0 if not isinstance (sentence, str): return None for letter in sentence: if letter in "aeiouAEIOU" count 1 return count def sumEven(f, t): total 0 if not isinstance(f, int) or not isinstance(t, int): return None for i in range(f, t+1): total i return total

def countVowels(sentence):

count = 0

if not isinstance(sentence, str):

return None

for letter in sentence:

if letter in "aeiouAEIOU":

count += 1

return count

def sumEven(f, t):

total = 0

if not isinstance(f, int) or not isinstance(t, int):

return None

for i in range(f, t+1):

if i % 2 == 0:

total += i

return total

print(countVowels("Cauliflower"))

print(countVowels(123))

print(sumEven(1, 10))

print(sumEven(1, 'qw'))
