# /*
#  * EJERCICIO:
#  * - Crea ejemplos utilizando todos los tipos de operadores de tu lenguaje:
#  *   Aritméticos, lógicos, de comparación, asignación, identidad, pertenencia, bits...
#  *   (Ten en cuenta que cada lenguaje puede poseer unos diferentes)

# Aritméticos
print(2 + 2)
print(2 - 2)
print(2 * 2)
print(3 / 2)
print(3 // 2)
print(2 % 2)
print(2 ** 2)

# lógicos
print(True and True)
print(True or True)
print(not True)

# comparación
print(2 == 2)
print(2 != 2)
print(2 > 2)
print(2 < 2)
print(2 >= 2)
print(2 <= 2)

# asignación
a = 2
print(a)
a += 2
print(a)
a *= 2
print(a)
a **= 2
print(a)
a -= 2
print(a)
a /= 2
print(a)
a //= 2
print(a)
a %= 2
print(a)
if test := 5 + 5:
    print(test)

dicc = {'test': 2}
dicc2 = dicc

# identidad
print(dicc is dicc2)

# pertenencia
print('test' in dicc2)

# bits
a = 0b1010
b = 0b1101

print(~15)
print(~(-15))
print(a & b)
print(a | b)
print(a ^ b)

print(2 << 4)
print(21 >> 4)

#  * - Utilizando las operaciones con operadores que tú quieras, crea ejemplos
#  *   que representen todos los tipos de estructuras de control que existan
#  *   en tu lenguaje:
#  *   Condicionales, iterativas, excepciones...
#  * - Debes hacer print por consola del resultado de todos los ejemplos.
