A receipt printed out in Python programming I have been trying to do it but it gives me an error for some reason and I'm at a loss. 

Here is the code Im using :

producto1 = input("Entre producto 1: ")

producto2 = input("Entre producto 2: ")

producto3 = input("Entre producto 3: ")

producto4 = input("Entre producto 4: ")

producto5 = input("Entre producto 5: ")

a = "$10:00"

b = "$6:00"

c = "$2:84"

d = "$3:18"

e = "$2:99"

f = "$4:80"

g = "$5:00"

h = "$3:00"

i = "$1:00"

print("")

Titulo = "Prog 3360L Tarea 2.2"

print(Titulo.title().cneter(48))

print("=" * 50)

print(producto1.1just)(30)+ a.rjust(20)

print(producto2.1just)(30)+ b.rjust(20)

print(producto3.1just()30)+ c.rjust(20)

print(producto4.1just)(30)+ d.rjust(20)

print(producto5.1just)(30)+ e.rjust(20)

 

print("=" * 50)

print("Total en compra.....:".1just)(30) + f.rjust(20)

print("IVU Estatal (10.5%).:".1just)(30) + g.rjust(20)

print("IVU Municipal (1%)..:".1just)(30) + h.rjust(20)

print("Total a pagar.......:".1just)(30) + i.rjust(20)

print("=" * 50)

print("Propina sugerida:".1just(30))

print("15% -> $5.00".1just(30))

print("20% -> $7.00".1just(30))

print("25% -> $9.00".1just(30))

print("=" * 50)

print("***Gracias***".center(48))
