Explicación:
|
|
Un string es una cadena de carácteres, a diferencia de C donde las cadenas son un arreglo de carácteres, en python se los conisidera un tipo más y en ésta entran cualquier carácter unicode y pueden ser impresas en consola como
|
|
un texto más.
|
|
Una lista es una colección de datos de cualquier tipo, indexados y editables en cualquier momento, se usan como los arreglos tradicionales, solo que con la diferencia de que éstos últimos, en las listas se admite cualquier tipo
|
|
de dato.
|
|
Una tupla es una colección de datos de cualquier tipo, ordenados y no intercambiables ni editables. Suelen ser usados para ser devueltos en una función con múltiples retornos.
|
|
|
|
def rand(): return int1, int2 ==> integer1, integer2 = rand()
|
|
Un conjunto es una colección de elementos únicos sin indexar, en python se usan para guardar datos únicos y sin repetir
