How to use the title() method in Python?

Question

How do I use the title() in Python in a list, tuple, set?

Exemplos que não executam:

lista = ['banana', 'mamão', 'maçã']
print (lista.title())

tupla = ('banana', 'mamão', 'maçã')
print (tupla.title())

seta = {'banana', 'mamão', 'maçã'}
print (seta.title())

The function title() is a function that is associated with str of Python, that is, you can only use it if it is in a string. If you have a list of strings and wants each of the list to be capitalized with the function title, you have to scroll through the list and add the function title for each of them, this serves for any interfacing in Python, as list, set, tuple, etc. A simple way to do this without having to create a block for to go through your strings is using the comprehensions of Python, it would look like this.

lista =['laranja', 'mamão', 'maçã']
nova_lista_captalizada = [ i.title() for i in lista]


tupla = ('banana', 'mamão', 'maçã')
nova_tupla = tuple( i.title() for i in tupla)

# O modo de cima é a mesma coisa que a debaixo
nova_lista_captalizada =[]
for i in lista:
     nova_lista_captalizada.append(i.title())

If you still don’t know the comprehensions in Python, no problem, you need to understand here, that function title(), is related to str in Python.
