Python Program List 2

111.      Write a Python program to get a string and print n (non-negative integer) copies of a given string using function.

def larger_string(str, n):

   result = ""

   for i in range(n):

      result = result + str

   return result

print(larger_string('patel', 2))

print(larger_string('.py', 3))

Output:

patelpatel

                                .py.py.py

212.      Write a Python program to find whether a given number (accept from the user) is even or odd, print out an appropriate message to the user.

num = int(input("Enter a number: "))

mod = num % 2

if mod > 0:

    print("This is an odd number.")

else:

    print("This is an even number.")

Output:

Enter a number: 5                                                                                            

This is an odd number.

313.      Write a Python program to test whether a passed letter is a vowel or not.

def is_vowel(char):

    all_vowels = 'aeiou'

    return char in all_vowels

print(is_vowel('c'))

print(is_vowel('e'))

Output:

Flase

True

414.      Write a Python program to check whether a specified value is contained in a group of values.

def is_group_member(group_data, n):

    for value in group_data:

        if n == value:

            return True

    return False

print(is_group_member([1, 5, 8, 3], 3))

print(is_group_member([5, 8, 3], -1))

Output:

True

False

515.      Write a Python program to create a histogram from a given list of integers.

def histogram( items ):

    for n in items:

        output = ''

        times = n

        while( times > 0 ):

          output += '*'

          times = times - 1

        print(output)

histogram([2, 3, 6, 5])

Output:

**                                                                                                           

***                                                                                                          

******                                                                                                       

*****

616.      Write a Python program to compute the greatest common divisor (GCD) of two positive integers.

def gcd(x, y):

    gcd = 1

   

    if x % y == 0:

        return y

   

    for k in range(int(y / 2), 0, -1):

        if x % k == 0 and y % k == 0:

            gcd = k

            break 

    return gcd

print(gcd(12, 17))

print(gcd(4, 6))

Output:

1

717.      Write a Python program to display your details like name, age, address in three different lines.

def personal_details():

    name, age = "Piyush", 30

    address = "Rajkot, Gujarat, India"

    print("Name: {}\nAge: {}\nAddress: {}".format(name, age, address))

personal_details()

Output:

Name: Piyush

Age: 30                                                                                          

Address: Rajkot, Gujarat, India

818.      Write a Python program to get OS name, platform and release information.

import platform

import os

print(os.name)

print(platform.system())

print(platform.release())

Output:

919.      Write a Python program to sum of three given integers. However, if two values are equal sum will be zero.

def sum(x, y, z):

    if x == y or y == z or x==z:

        sum = 0

    else:

        sum = x + y + z

    return sum

print(sum(2, 1, 2))

print(sum(3, 2, 2))

print(sum(2, 2, 2))

print(sum(1, 2, 3))

0

0

0

120.  Write a python program to sum of the first n positive integers.

n = int(input("Input a number: "))

sum_num = (n * (n + 1)) / 2

print(sum_num)

Output:

Input number: 10
