Merge two strings

 Merge two strings by taking characters alternatively from each string

Sample string 1 :  PYTHON
Sample string 2 :  python
Output:  PpYyTtHhOoNn 

Let us understand the two scenarios of this problem

Scenario1:  If both the strings are of same length:

string1=input("Enter first string: ")
string2=input("Enter second string: ")
i,j=0,0 # object initialization using Tuple Unpacking
result=""
while i<len(string1) or j<len(string2):
	result=result+string1[i]+string2[j]
	i=i+1
	j=j+1
print("You entered first string : ",string1)
print("You entered second string : ",string2)
print("Final result after alternate merge: \n", result )

Scenario 2:  If the strings have different length:

string1=input("Enter first string: ")
string2=input("Enter second string: ")
i,j=0,0 # object initialization using Tuple Unpacking
result=""
while i<len(string1) or j<len(string2):
	if i<len(string1):
		result=result+string1[i]
		i=i+1
	if j<len(string2):
		result=result+string2[j]
		j=j+1
print("You entered first string: ",string1)
print("You entered second string: ",string2)
print("Final result after alternate merge: \n", result )
