Assignment operators in Python, and in other language programming, are used to assign values ​​to variables.

For example, if we indicate a = 5 and b = 3 we are assigning the value 5 to the variable a and the value 3 to the variable b.

But let’s see in detail what other assignment operators exist:

### Assignment Operators Python = assign

Example:

a = 5 assigns the value 5 to the variable a on the left (ie what is to the right of the equal.)

Another example could be a = b + c where to a this time we assign the sum b + c.

### Assignment Operators Python += add and assign

Assigns the sum between it and the right operand to the left operand.

For example:

a += 2 is equivalent to doing a = a + 2, so it assigns to the variable a on the left the value of a (we always suppose a = 5) added to 2. So we will get a = 7.

### Assignment Operators Python -= subtract and assign

Assigns the difference between it and the right operand to the left operand.

Ex:

a – = 2 is equivalent to doing a = a-2, so it assigns to the variable a on the left the value of a (we always assume a = 5) minus 2. So we will get a = 3.

### Assignment Operators Python *= multiply and assign

Assigns the product between it and the right operand to the left operand.

An example:

a * = 2 is equivalent to doing a = a * 2, so it assigns to the variable a on the left the value of a (let’s always suppose a = 5) multiplied by 2. So we will get a = 10.

### Assignment Operators Python /= divide and assign

Assigns the real division between it and the right operand to the left operand.

As for example:

a /= 2 is equivalent to doing a = a / 2, so it assigns to the variable a on the left the value of a (we always assume a = 5) divided by 2. So we will get a = 2.5.

### Assignment Operators Python //= divide and assign

Assign the rounded division between it and the right operand to the left operand.

Eg: a //= 2 is equivalent to doing a = a // 2, so it assigns the value of a to the variable a on the left (we always assume a = 5) divided by 2 rounded to the integer. So we will get a = 2.

### Assignment Operators Python %= calculate the remainder and assign

Assigns to the left operand the remainder obtained from the division between it and the right operand.

Example:

a%= 2 is equivalent to doing a = a% 2, so it assigns the value of a to the variable a on the left (we always assume a = 5) divided by 2 rounded to the integer. So we will get a = 1.

### Assignment Operators Python **= calculate the power and assign

Assigns to the left operand the result of exponentiation of it as the base and exponent of the right operand.

Example:

a **= 2 is equivalent to doing a=a2, so it assigns to the variable a on the left the value of a (we always suppose a = 5) raised to 2. So we will get a = 25.

Try these simple examples interactively to familiarize yourself with the language.

### Some exercises

Some exercises on assignment operators in Python

``````
a = 10
b = 15 + a
c = b * 2
c += 1

print(a,b,c)
``````

### Other exercises

``````

a = b = c = 10

a *= 10
b **= 2
c //= 4

print(a,b,c)
``````

In this lesson we have studied the assignment operators in Python and have seen many exercises and practical examples.
