Question

String Product Function Name: string Multiply Parameters: sentence (str), num (int) Returns: product (int) Description: You're texting your friend when you notice that they replace many letters with numbers. Out of curiosity, you want to find the product of the numbers. Write a function that takes in a string sentence and an int num, and find the product of only the first num numbers in the sentence. If num is 0, return 0. If num > O but there aren't any numbers in the string, return 1. If num is greater than the amount of numbers in the sentence, return the product of all the numbers. (Hint: the isdigit() method may be helpful.) >>> sentence = "h3110 n1c3 2 m33t u" >>> num = 6 >>> print(stringMultiply(sentence, num)) >>> sentence = "Anthony 4nd arvin were h3r3" >>> num = 10 >>> print(stringMultiply(sentence, num)) 144

Answer 1

All the explanation is in the code comments. Hope this helps!

Code:

# required function
def stringMultiply(sentence, num):
  
# return 0 for num = 0
if(num <= 0):
return 0
  
# the total product
p = 1
  
# loop through all the characters of the string
for c in sentence:
  
# check if c is digit
if(c.isdigit()):
  
# update product
p = p * int(c)
# update the num
num = num - 1
  
# break if num becomes 0
if(num == 0):
break
return p
  
# sample run
sentence = "h311o n1c3 2 m33t u"
num = 6
print(stringMultiply(sentence, num))
  
sentence = "4nthony 4nd arv1n were h3r3"
num = 10
print(stringMultiply(sentence, num))

Sample run:

27 # sample run 28 sentence "h311o n1c3 2 m33t u" %3D 29 num = 30 print(stringMultiply(sentence, num)) 31 32 sentence "4nthony 4nd arv1n were h3r3" 33 10 num 34 print(stringMultiply(sentence, num)) 35 18 144
