add 2 binary numbers python code example

Example 1: python multiply list bt number

my_list = [1, 2, 3, 4, 5]
my_new_list = [i * 5 for i in my_list]

>>> print(my_new_list)
[5, 10, 15, 20, 25]

Example 2: binary addition in python

#Efficient Binary Addition

def binaryAddEfficient(a, b):
   if len(a)< len(b):
      a = (len(b)-len(a))*'0'+a
   elif len(b)<len(a):
      b = (len(a)-len(b))*'0'+b

   sumList=[]  #Using a list instead of a string
   carryover=0

   for i in range(len(a)-1, -1,-1):
        sum = (int(a[i]) + int(b[i]) +carryover) % 2    
        carryover = (int(a[i]) + int(b[i]) +carryover) // 2
        sumList.append(str(sum))  #Appending to the list on the right.

   if carryover:
        sumList.append(str(carryover))

   sumList.reverse()  #Reverse, because appending gets done on the right.
   return "".join(sumList)

Example 3: multiplication of string with int in python

#multiplying string with a integer
"superman " * 5
# It will return a new string
