Cara menggunakan sort integer list python

Question

Try this, it'll sort the list in-place in descending order (there's no need to specify a key in this case):

Append python buat apa?
Langkah pertama yang harus dilakukan dalam algoritma atau teknik selection sort adalah?
Struktur data pada python yang mampu menyimpan lebih dari satu data dimana setiap data memiliki index bilangan bulat berurutan yang dimulai dari 0 disebut?

listB = [24, 13, -15, -36, 8, 22, 48, 25, 46, -9]
listB.sort(reverse=True) # listB gets modified

print listB
=> [48, 46, 25, 24, 22, 13, 8, -9, -15, -36]

Alternatively, you can create a new sorted list:

listB = [24, 13, -15, -36, 8, 22, 48, 25, 46, -9]
listC = sorted(listB, reverse=True) # listB remains untouched

print listC
=> [48, 46, 25, 24, 22, 13, 8, -9, -15, -36]

Python list sort() function can be used to sort a List in ascending, descending, or user-defined order. In each case, the time complexity is O(nlogn) in Python.

Syntax of sort() function

Syntax:
List_name.sort(reverse=True/False, key=myFunc)
Parameter:
reverse: (Optional), reverse=True will sort the list descending. Default is reverse=False
key Optional. A function to specify the sorting criteria(s)

Example 1: Sort the List of numbers in Ascending Order

The sort() method by default sort element in ascending order as we can see below example:

Python3

# Python program to demonestrate to

# sorting numbers in Ascending Order

numbers= [

[1, 2, 3, 4]

0

[1, 2, 3, 4]

1

[1, 2, 3, 4]

2

[1, 2, 3, 4]

1

[1, 2, 3, 4]

4

[1, 2, 3, 4]

1

[1, 2, 3, 4]

6

[1, 2, 3, 4]

7

[1, 2, 3, 4]

8

[1, 2, 3, 4]

9

['code', 'geeks', 'ide', 'practice']

0

['code', 'geeks', 'ide', 'practice']

1

[1, 2, 3, 4]

9

['code', 'geeks', 'ide', 'practice']

3

['code', 'geeks', 'ide', 'practice']

4

[1, 2, 3, 4]

9

['code', 'geeks', 'ide', 'practice']

6

['code', 'geeks', 'ide', 'practice']

7

['code', 'geeks', 'ide', 'practice']

8

['code', 'geeks', 'ide', 'practice']

4

[1, 2, 3, 4]

9

[4, 3, 2, 1]

1

[4, 3, 2, 1]

2

[4, 3, 2, 1]

3

Output:

[1, 2, 3, 4]

Example 2: Sort the List of alphabets in Ascending Order

The sort() method sorts the list in order from A-Z, to a-z in the alphabet.

Python3

[4, 3, 2, 1]

4

[4, 3, 2, 1]

5

[4, 3, 2, 1]

6= [

[4, 3, 2, 1]

9

[1, 2, 3, 4]

1

[(1, 1), (1, 2), (3, 3)]
[(3, 3), (1, 2), (1, 1)]

1

[1, 2, 3, 4]

1

[(1, 1), (1, 2), (3, 3)]
[(3, 3), (1, 2), (1, 1)]

3

[1, 2, 3, 4]

1

[(1, 1), (1, 2), (3, 3)]
[(3, 3), (1, 2), (1, 1)]

5

[1, 2, 3, 4]

7

[1, 2, 3, 4]

8

[(1, 1), (1, 2), (3, 3)]
[(3, 3), (1, 2), (1, 1)]

8

[(1, 1), (1, 2), (3, 3)]
[(3, 3), (1, 2), (1, 1)]

9

[1, 2, 3, 4]

9# Python program to demonestrate to1

Output:

['code', 'geeks', 'ide', 'practice']

Example 3: Sort the List in Descending Order

Here, we are sorting the list of numbers in Descending order, the same will be for alphabets(Z-A, z-a).

Python3

# Python program to demonestrate to

# Python program to demonestrate to3

# Python program to demonestrate to4

numbers= [

[1, 2, 3, 4]

0

[1, 2, 3, 4]

1

[1, 2, 3, 4]

2

[1, 2, 3, 4]

1

[1, 2, 3, 4]

4

[1, 2, 3, 4]

1

[1, 2, 3, 4]

6

[1, 2, 3, 4]

7

# sorting numbers in Ascending Order6

# sorting numbers in Ascending Order7= # sorting numbers in Ascending Order9numbers0

[1, 2, 3, 4]

9numbers2

Output:

[4, 3, 2, 1]

Example 4: Sorting using User-defined Order

In this example, we are sorting elements using the function based by passing the function to the key parameter of the sort() function.

Langkah langkah metode selection sort?

Memulai pengecekan data dari data ke 1 hingga data ke n..

Menentukan bilangan dengan index terkecil dari data pada bilangan tersebut..

Menukar bilangan index terkecil dengan bilangan pertama..

Begitu seterusnya hingga data berhasil diurutkan semuanya..

Append python buat apa?

Append. Salah satu fitur dalam array python yang cukup sering digunakan adalah fungsi append. Fungsi append ini berguna untuk menambahkan nilai array pada urutan terakhir. Fungsi ini sedikit berbeda dengan fungsi insert, dimana fungsi insert bisa menambahkan nilai array pada posisi tertentu.
