Python Program List 3


121.      Write a Python program to convert the distance (in feet) to inches, yards, and miles.

d_ft = int(input("Input distance in feet: "))
d_inches = d_ft * 12
d_yards = d_ft / 3.0
d_miles = d_ft / 5280.0

print("The distance in inches is %i inches." % d_inches)
print("The distance in yards is %.2f yards." % d_yards)
print("The distance in miles is %.2f miles." % d_miles)

Output:
Input distance in feet: 100                                                                                   
The distance in inches is 1200 inches.                                                                       
The distance in yards is 33.33 yards.                                                                        
The distance in miles is 0.02 miles.

222.      Write a Python program to convert seconds to day, hour, minutes and seconds.

time = float(input("Input time in seconds: "))
day = time // (24 * 3600)
time = time % (24 * 3600)
hour = time // 3600
time %= 3600
minutes = time // 60
time %= 60
seconds = time
print("d:h:m:s-> %d:%d:%d:%d" % (day, hour, minutes, seconds))

Output:
Input time in seconds: 1234565                                                                               
d:h:m:s-> 14:6:56:5

323.      Write a Python program to calculate the sum of the digits in an integer.

num = int(input("Input a four digit numbers: "))
x  = num //1000
x1 = (num - x*1000)//100
x2 = (num - x*1000 - x1*100)//10
x3 = num - x*1000 - x1*100 - x2*10
print("The sum of digits in the number is", x+x1+x2+x3)

Output:
Input a four digit numbers: 5245                                                                             
The sum of digits in the number is 16

424.      Write a Python program to get the command-line arguments (name of the script, the number of arguments, arguments) passed to a script.

import sys
print("This is the name/path of the script:"),sys.argv[0]
print("Number of arguments:",len(sys.argv))
print("Argument List:",str(sys.argv))

Output:
python test.py arg1 arg2 arg3

This is the name/path of the script: test.py
('Number of arguments:', 4)
('Argument List:', "['test.py', 'arg1', 'arg2', 'arg3']")

525.      Write a Python program to swap two variables.

a = 30
b = 20
print("\nBefore swap a = %d and b = %d" %(a, b))
a, b = b, a
print("\nAfter swapping a = %d and b = %d" %(a, b))
print()

Output:
Before swap a = 30 and b = 20                                                                                
After swapping a = 20 and b = 30

626.      Write a Python program to check if a number is positive, negative or zero.

num = float(input("Input a number: "))
if num > 0:
   print("It is positive number")
elif num == 0:
   print("It is Zero")
else:
   print("It is a negative number")

727.      Write a Python program to compute the product of a list of integers (without using for loop).

from functools import reduce
nums = [10, 20, 30,]
nums_product = reduce( (lambda x, y: x * y), nums)
print("Product of the numbers : ", nums_product)

Product of the numbers :  6000

828.      Write a python program to convert decimal to hexadecimal.

x = 30
print(format(x, '02x'))
x = 4
print(format(x, '02x'))

1e
04

929.      Write a Python program to check if lowercase letters exist in a string.

str1 = 'A8238i823acdeOUEI'
print(any(c.islower() for c in str1))

True

130.  Write a Python function to check whether a number is divisible by another number. Accept two integer’s values form the user.

def multiple(m, n):
                return True if m % n == 0 else False

print(multiple(20, 5))
print(multiple(7, 2))

True
False
