Answer :-

str1 = input("Enter first string = ")
str2 = input("Enter second string = ")
if len(str1) > len(str2) :
    big,small = str1 , str2
else :
    big , small = str2 , str1
print("big word ", big)
print ("smaller word ", small)
length = len(big)
step = length // 2
for i in range (step) :
    for j in range (length) :
        if j < step :
            if i == j :
                print (big [ j ], end ="")
            else :
                print ( " " , end = "")
        else :
            if j == length -i -1 :
                print (big [ j ], end = "")
            else :
                print (" ", end = "")
    print ()
if length % 2 == 1 :
    for i in range (step):
        print (" ", end = "")

    print (big [step])

Output :-

Enter first string = Path
Enter second string = Walla
big word  Walla
smaller word  Path
W   a
 a l
  l
>>> 

Enter first string = Portal
Enter second string = Path
big word  Portal
smaller word  Path
P    l
 o  a
  rt  
>>> 

Enter first string = Express
Enter second string = Portal
big word  Express
smaller word  Portal
E     s
 x   s
  p e  
   r
>>>
