+
+    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
