Program to find two largest numbers using Python

nums = [10, 90, 80, 60, 50]
maxone = 0
maxtwo = 0
for x in nums:
if(maxone < x):
maxtwo = maxone
maxone = x

elif (maxtwo < x):
maxtwo = x

print "First two largest numbers"
print "First largest number:", maxone
print "First largest number:", maxtwo


output:

First two largest numbers
First largest number: 90
First largest number: 80

Conversion of decimal to hexadecimal, binary and octal in Python

#num= int(input("Enter a decimal number:))
num = 15
print "Decimal value of given number:", num

print "Octal value of", num, ":",oct(num)
print "Binary value of", num, ":",bin(num)
print "Hexadecimal value of", num, ":",hex(num)

Output:

Decimal value of given number: 15
Octal value of 15 : 017
Binary value of 15 : 0b1111
Hexadecimal value of 15 : 0xf

To interchange key value pairs of a dictionary object in Python

dt = {'a': '1', 'b' : '2', 'c': '3', 'd': '4'}
print "Original dictionary:", dt
dt1 = {}
for (x, y) in dt.iteritems():
(x,y) = (y,x)
dt1.update(dict([(x,y)]))
print "After interchanging key value pairs:", dt1

Output:

Original dictionary: {'a': '1', 'c': '3', 'b': '2', 'd': '4'}
After interchanging key value pairs: {'1': 'a', '3': 'c', '2': 'b', '4': 'd'}

Sorting a list with out sort/sorted functions - Python

lst = [1,0,4,5,6,7,8,0,0,0]

print(lst)
cou = len(lst)
for i in range(cou):
    for j in range(1, cou-i):
       #descending
        """if lst[j] > lst[j-1]:
            (lst[j-1], lst[j]) = (lst[j], lst[j-1])"""
        #ascending  
        if lst[j] < lst[j-1]:
            (lst[j-1], lst[j]) = (lst[j], lst[j-1])
print(lst)

Reverse each word in a sentence - Python

# your code goes here

st = "This is awesome!"

st1 = st.split(" ")
st2 = ''
st3 = []

print st1

for y in st1:
#print y
ls = len(y)
for x in range(len(y)):
st2 = st2 + y[ls - 1 -x]
st2 = st2 + ' '
st3.append(st2)
print ' '.join(st3)
