convert tuple to list

#convert a list of numbers into tuple

#defining list
l=[]

#entering numbers into list
ch='y'
while(ch!='n'):
    n=int(input("enter no:"))
    l.append(n)
    ch=input('do you want to continue:')

#to display list
print('list of entered numbers:',l)

#to display tuple
print('tuple of list:',tuple(l))

OUTPUT:

   

swapping of two numbers

#swapping of two numbers


#taking two numbers from user
a=int(input('enter first number:'))
b=int(input('enter second number:'))

#to display the entered numbers
print("first number:",a)
print('second number:',b)


#to swap the numbers
a,b=b,a

#to display the numbers after swapping
print('after swapping of numbers')
print("first number:",a)
print('second number:',b)


OUTPUT:

sum of digits of number

n=int(input("enter no:"))
sum=0
while(n!=0):
    r=n%10
    n=n//10
    sum=sum+r
print("sum of digits:",sum)

Convert a number to BINARY DIGIT

d=1
bin=0
n=int(input("enter no.:"))
while(n!=0):
    r=n%2
    bin=r*d+bin
    d=d*10
    n=n//2
print(bin)
