**Given a list of the elements and we have to sort the list in Ascending and the Descending order in Python.**

**给定一个元素列表，我们必须按Python的升序和降序对列表进行排序。**

## Python list.sort()方法 **(**Python list.sort() Method**)** ##

sort() is a inbuilt method in Python, it is used to sort the elements/objects of the list in Ascending and Descending Order.

sort()是Python中的内置方法，用于按升序和降序对列表中的元素/对象进行排序。

**Sorting elements in Ascending Order (list.sort())**

**升序排序元素(list.sort())**

**Syntax:**

**句法：**

list.sort()

**Program to sort list elements in Ascending Order**

**程序以升序对列表元素进行排序**

# List of integers
    num = [10, 30, 40, 20, 50]
    
    # sorting and printing 
    num.sort()
    print (num)
    
    # List of float numbers
    fnum = [10.23, 10.12, 20.45, 11.00, 0.1]
    
    # sorting and printing
    fnum.sort()
    print (fnum)
    
    # List of strings 
    str = ["Banana", "Cat", "Apple", "Dog", "Fish"]
    
    # sorting and  printing
    str.sort()
    print (str)

**Output**

**输出量**

[10, 20, 30, 40, 50]
        [0.1, 10.12, 10.23, 11.0, 20.45]
        ['Apple', 'Banana', 'Cat', 'Dog', 'Fish']

**Sorting in Descending Order (list.sort(reverse=True))**

**降序排序(list.sort(reverse = True))**

To sort a list in descending order, we pass reverse=True as an argument with sort() method.

要按降序对列表进行排序，我们使用sort()方法将reverse = True作为参数传递。

**Syntax:**

**句法：**

list.sort(reverse=True)

**Program to sort list elements in Descending Order**

**程序以降序对列表元素进行排序**

# List of integers
    num = [10, 30, 40, 20, 50]
    
    # sorting and printing 
    num.sort(reverse=True)
    print (num)
    
    # List of float numbers
    fnum = [10.23, 10.12, 20.45, 11.00, 0.1]
    
    # sorting and printing
    fnum.sort(reverse=True)
    print (fnum)
    
    # List of strings 
    str = ["Banana", "Cat", "Apple", "Dog", "Fish"]
    
    # sorting and  printing
    str.sort(reverse=True)
    print (str)

**Output**

**输出量**

[50, 40, 30, 20, 10]
        [20.45, 11.0, 10.23, 10.12, 0.1]
        ['Fish', 'Dog', 'Cat', 'Banana', 'Apple']
