Python Program For O level Practical

1
Python Program

• Python is a well-liked programming language. It
  was developed by Guido van Rossum in 1991. It is
  used for web development (server-side), software
  development, mathematics, system scripting.
  Python was designed for readability, and has some
  similarities to the English language with
  manipulate from mathematics.

Python program to calculate the factorial of a
number

• Program
• def fact(n)
• if n 0
• return 1
• else
• return n fact(n-1)

NumPy program to find the most frequent value in
the list.

• Program
• import numpy as np
• x np.array(1,2,3,4,5,7,2,1,1,1,8,9,1)
• print(x)
• print("most frequent value in the list")
• print(np.bincount(x).argmax())
• Output
• 1 2 3 4 5 7 2 1 1 1 8 9 1
• most frequent value in the list
• 1

4
Python program accept a hyphen-separated sequence
of words as input and prints the sorted words

• Program
• print("Enter words separated by Hyphens ")
• lst n for n in input().split("-")
• lst.sort()
• print('-'.join(lst))
• Output
• Enter words separated by Hyphens
• gaurav-ram-yashir-bittu-wong
• bittu-gaurav-ram-wong-yashir

5
Python function that takes two lists and returns
True if they have at least one common item.

• Program
• def data(lst1, lst2)
• result False
• for i in lst1
• for j in lst2
• if i j
• result True
• return result
• print(data(1,2,3,4,5, 5,6,7,8,9,10))

6
Python program to compute Fibonacci series using
function.

• Program
• def fab(x)
• if xlt2
• return 1
• else
• return fab(x-1)fab(x-2)
• yint(input("Enter a number "))
• for i in range(y)
• print(i, "", fab(i))

7
Python program to multiply two numbers by
repeated addition

• Program
• a int(input("Enter the first number "))
• b int(input("Enter the second number "))
• product 0
• for i in range(b)
• product producta
• print(product)
• Output
• Enter the first number 3
• Enter the second number 4
• 12

8
Python program to find the power of a number
using recursion

• Program
• Hello Students this program is very useful for O
  Level Practical so read it carefully.
• def power(x,y)
• if y0
• return 1
• else
• return x power(x, y-1)
• x float(input("Enter a value of base "))
• y int(input("Enter value of exponent "))
• result power(x, y)
• print(result)
• Output
• Enter a value of base 2
• Enter value of exponent 3
• 8.0

9
Python Program to Sort Python Dictionaries by Key
or Value

• mydict 'raj' 5, 'raja' 6,
• 'sanju' 7, 'mohan' 2, 'surya' 10
• Keys list(mydict.keys())
• Keys.sort()
• sort_dict i mydicti for i in Keys
• print(sort_dict)

10
Python Program to find largest element from the
list which provided by user

• list
• num int(input("Enter number of elements in
  list "))
• for i in range(1, num 1)
• a int(input("Enter elements "))
• list.append(a)
• print("Largest element is", max(list))
• Output
• Enter number of elements in list 3
• Enter elements 19
• Enter elements 13
• Enter elements 88
