Lists sangat mirip dengan array. Mereka dapat berisi jenis variabel apa pun, dan dapat berisi sebanyak mungkin variabel yang Anda inginkan. Lists juga dapat diiterasi dengan cara yang sangat sederhana. Berikut adalah contoh cara membangun sebuah list.
```python mylist = [] mylist.append(1) mylist.append(2) mylist.append(3) print(mylist[0]) # mencetak 1 print(mylist[1]) # mencetak 2 print(mylist[2]) # mencetak 3
mencetak 1,2,3
for x in mylist: print(x) ```
Mengakses indeks yang tidak ada akan menghasilkan pengecualian (error).
python
mylist = [1,2,3]
print(mylist[10])
Exercise
Dalam latihan ini, Anda perlu menambahkan angka dan string ke list yang sesuai menggunakan metode "append" untuk list. Anda harus menambahkan angka 1, 2, dan 3 ke list "numbers", dan kata-kata 'hello' dan 'world' ke variabel strings.
Anda juga harus mengisi variabel second_name dengan nama kedua dalam list names, menggunakan operator kurung siku []. Perhatikan bahwa indeks dimulai dari nol, jadi jika Anda ingin mengakses item kedua dalam list, indeksnya adalah 1.
numbers = []
strings = []
names = ["John", "Eric", "Jessica"]
# write your code here
second_name = None
# this code should write out the filled arrays and the second name in the names list (Eric).
print(numbers)
print(strings)
print("The second name on the names list is %s" % second_name)
numbers = []
strings = []
names = ["John", "Eric", "Jessica"]
# write your code here
numbers.append(1)
numbers.append(2)
numbers.append(3)
strings.append("hello")
strings.append("world")
second_name = names[1]
# this code should write out the filled arrays and the second name in the names list (Eric).
print(numbers)
print(strings)
print("The second name on the names list is %s" % second_name)
test_output_contains("[1,2,3]", no_output_msg= "Make sure that you have printed the `numbers` list.")
test_output_contains("['hello', 'world']", no_output_msg= "Make sure that you have printed the `strings` list.")
test_output_contains("The second name on the names list is Eric", no_output_msg= "Did you fill in the variable `second_name` with the second name in the names list?")
success_msg("Great Job!")
