Python code error (line 4) [closed]

I have a syntax error in line 4 of the code, in the print. Help please.

a=float(input('Introduzca una nota del 0 al 10: ')

if 0<=a>5 
   print('Suspendido')
elif 5<=a>8 
  print('Aprobado')
elif 8<=a>9.5 
  print('Notable')
elif 9.5<=a>=10
  print('Sobresaliente')
else :
  print('La nota introducida no es válida')
