Making a copy list in a function - RuyCab - Jul-11-2021
I'm getting a error in the function (make_great). I saw that we use [:] to pass a copy of the list to a function, but it's not working.
Does someone understand why this problem is occurring ?
def show_magicians(magicians_list):
for indice, magician in enumerate(magicians_list):
print(f'Magician {indice+1}: {magician}')
def make_great(magicians_list[:]):
list_aux = []
for magician in magicians_list:
magician = 'O grande ' + magician
list_aux.append(magician)
return list_aux
magicians_aux = make_great(magicians)
show_magicians(magicians)
show_magicians(magicians_aux)

def make_great(magicians_list[:]):Don't use [:] on the parameter
Use [:] inside the function
def make_great(magicians_list):
list_aux = []
for magician in magicians_list[:]:
...
...If you actually want to pass in a copy of the list and the function uses the passed-in list, use
magicians_aux = make_great(magicians[:])
def make_great(magicians_list):
list_aux = []
for magician in magicians_list:
...
