I am trying to write a code that asks an User to Enter a decimal number, the my program should separate the number in two parts like this:
1 cae:Enter a number: 12.9Decimal part: 12whole part : 9
2 case:Enter: 10Decimal par:Whole part: 10
That is my code: 
A = input("Enter a number")
C = [ ]     for  i  in  str(A) :
      C.append(i)      if i ==".# period ":         break      aa= "".join(c)   print(aa, end =" ")
   if i == int(A):         print(" It is the whole part")
I can not display the whole part when I enter float number. Plus when I enter an integer, it takes that enteger as a decimal number. Any help?
