Syntax:

list_name.sort(reverse=True/False, key=fucntion_name)

reverse – optional parameter. reverse=True will sort in descending order. Default value of reverse is False.
key – optional parameter. a function to specify the sorting criteria

Example 1:

names = ['Chris', 'Navneet', 'Abu', 'Malu' ]
names.sort()
print(names)

Output:

['Abu', 'Chris', 'Malu', 'Navneet']

Example 2:

names = ['Chris', 'Navneet', 'Abu', 'Malu' ]
names.sort(reverse=True)
print(names)

Output:

['Navneet', 'Malu', 'Chris', 'Abu']

Example 3:

def leng(e):
    return len(e)
names = ['Chris', 'Navneet', 'Abu', 'Malu' ]
names.sort(key=leng)
print(names)

Output:
