Question

Can any one plz explain?

Answer 1

For exemple:
Python

print (a := 10)
# 10

print (a = 10)
# TypeError
...

Using this operator allows you to speed up and shorten your code.
makes it possible to solve two problems at once: assign a value to a variable and return that value, so sometimes you can write the code shorter and make it more readable, and it can be even more computationally efficient
