1. Write a recursive function to print the factorial for a given number.
2. def recur_factorial(n):
3. if n==1:
4. return
5. n
6. else:
7. return n*recur_factorial(n-1)
8. num=int(input("Enter Number"))
9. if num<0:
10. print("Enter valid number")
11. elif num==0:
12. print("factorial of 0 is 1")
13. else:
14. print("The factorial of",num,"is",recur_factorial(num))
15. Enter Number 5
16. The factorial of 5 is 120

19. a. Write a function that takes a character (i.e. a string of length 1) and returns True if it is a vowel,
20. False otherwise.
21. def isvowel(char):
22. all_vowel='aeiou'
23. return char in all_vowel
24. print(isvowel('a"))
25. print(isvowel('b'))

29. b. Define a function that computes the length of a given list or string
30. def len(s):
31. counter=0
32. for i in S:
33. counter+=1
34. return counter
35. s=input("enter string:")
36. print(len(s))
