  Here is the program for swapping first and last digits of a number in Python programming language program code : n=int(input("number:")) last=n%10 n=int(n/10) n1=str(n) n2=str(1) n6=str(1) for i in range(len(n1)-1):     n2=n2+str(0)     n6=n6+str(0) n6=int(n6) n2=int(n2) n5=int(n/n6) n3=n%n2 print(n5) n4=str(last)+str(n3)+str(n5) print(int(n4)) output : enter number :284517 784512 happy coding. comment what you need.
