a = 08
 print a
 File"<stdin>",line 1
 a = 08
      <
 syntax error:invalid token

(if I use 07, the 0 is supressed but it compiles & display the 7)

By prefixing a number with 0, you're actually using octal rather than 
decimal (i.e., only digits 0 to 7 are valid).  For example, try:

 >>> print 030
24
 >>> print 077
63
