How to sort a list in python?

The sort() function sorts the items of the list, by default in increasing order. This is done “in place”, i.e., it does not create a new list.

It is used in the following syntax:-

list.sort()

e.g.,

t1=['1', '4', '2', '6']
t1.sort()
print(t1)

output- ['1', '2', '4','6']

Like reverse(), sort() also performs its function and does not return anything.

To sort a list in decreasing order using sort(), we can use:-

list.sort(reverse=True)

t1=['1', '4', '2', '6']
t1.sort(reverse=True)
print(t1)

output=['6', '4', '2', '1']

Sort() has two parameters:-

• reverse- If True, list is sorted in descending order.
• key-function that serves as a key for the sort comparison.

t1=['python', 'blog', 'pythonpoint', 'Cpython']
t1.sort(key=len)
print(t1)

output-['blog', 'python', 'Cpython', 'pythonpoint']

This is all about sorting a list.
