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))

39. b. Define a function that computes the length of a given list or string
40. def len(s):
41. counter=0
42. for i in S:
43. counter+=1
44. return counter
45. s=input("enter string:")
46. print(len(s))

50. C.
51. example, histogram ([4, 9, 9, 7]) 7]) should print the following:
52. ****
53. def histogram(items):
54. for n in items:
55. output=''
56. times=n
57. while times>0:
58. output+='*'
59. times=times-1
60. þprintCoutput)
61. histogram([4,9,7])

65. Design a class that store the information of student and display the same
66. class student:
67. def info(self,name,city):
68. name=input("Enter name:")
69. city=input("Enter city:")
70. print("Name:",name,"City:",city)
71. 1/4
72. :::
73. obj=student()
74. obj.info('Name','City')
75. Enter name:Bob
76. Enter city:Atlanta
77. Name: Bob City: Atlanta

81.  
82. b. Implement the concept of inheritance using python
83. Note: Create polygon.py, rectangle.py and inherit.py file in same project run the inherit project
84. class polygon:
85. width=0
86. height=0
87. def set_values(self,width,height):
88. polygon.width=width
89. polygon.height=height
90. Python Programming Practical
91. S.Y.B.Sc (IT)
92. from polygon import*
93. class rectangle(polygon)
94. def area(self):
95. return self.width*self.height
96. from Rectangle import*
97. rect=rectangle()
98. rect.set_values(10,10)
99. print("Area of Rectangle:",rect.area())
100. Area of Rectangle: 100
