What is a Inplace Operations in Python?

Inplace Operations :

It is common within applications to need to have code like this:

a = a + 1

or

a = a * 2

There is an effective shortcut for these in place operations:

a += 1

and

a *= 2

Any mathematic operator can be used before the '=' character to make an inplace operation:

-= decrement the variable in place

+= increment the variable in place

*= multiply the variable in place

/= divide the variable in place

//= floor divide the variable in place # Python 3

%= return the modulus of the variable in place

**= raise to a power in place

Other in-place operators exist for the bitwise operators ( ^ , | etc)
