Write Python program with the following functions: A recursive function called s

Question

Write Python program with the following functions:

A recursive function called stutter that returns a string with each character in its argument repeated. For example, if the string passed to stutter is "abc", stutter will return the string "aabbcc".

A recursive function called toNumber that returns the integer sum of all digit characters in a string. For example, the result of toNumber("ab3c7d1") would be 11. Assume that the length of any empty string is 0. (Hint: you may use the method isdigit() to check whether or not a character is a digit.)

Add a main function to test your code.

Explanation / Answer

You have asked for a recursive implementation so i have tried doing that.

But without making these functions recursive also we can do the tasks mentioned above

assignment.py

def toNumber(text):
   if(len(text)==1):
       if text.isdigit():
           return int(text)
       else:
           return 0

   sum=0;
   for i in text:
       sum=sum+toNumber(i)
   return sum

def stutter(text):
   if(len(text)==1):
       return text*2

   newText=''
   for i in text:
       newText=newText+stutter(i);
   return newText

#for testing the methods
text="123xcde89"
sum=toNumber(text)
print sum

text="abc"
print stutter(text)
