If I write a code like:
def addstring(n):
a1=raw_input("PRINT THE FIRST STRING:")
a2=raw_input("PRINT THE SECOND STRING:")
a3=" "
a4=a1+a3+a2
print "THE TWO STRINGS YOU PRINTED ARE ADDED AS"
print a4
Now, if I design one HTML form where strings can be submitted but if I put one ADD button how would I integrate with addstring function?
