# How to Multiply Variables in Python

In this post, we will learn how to multiply variables in Python. Usually, when we multiply two variables, we use x×y, where x and y are variables.

However, in most programming languages, including Python, we use the * (asterisk) sign to multiply variables instead of ×. So, to take the product of two variables, we use x*y. Simple, right?

Let’s take an example.

```x = 2
y = 4
result = x*y
print("Result:", result)```

Output

`Result: 8`

In the above example, x contains 2, and y holds 4. We take the product, i.e., 2*4=8, and store it in the result variable. Finally, we display it.

## How to Multiply Variables in Python: Variables of type int or float

One thing to keep in mind while multiplying variables is that their types should be compatible.

So, if we want to perform arithmetic multiplication, all variables must be numbers, i.e., either integers or floating-point numbers.

Otherwise, the program will throw an error or provide unexpected results.

```x = 2.5
y = 3
z = 7.5
result = x*y*z
print("Result:", result)```

Output

`Result: 56.25`

Here, x and z are floating-point numbers, and y is an integer. We get the correct result that is of type float.

## How to Multiply Variables in Python: Variables of type int and string

Consider the following example.

```x = 2
y = 'abc'
result = x*y
print("Result:", result)```

Output

`Result: abcabc`

In the above example, x is of type integer and y of type string. In this case, using the * repeats the string by (x-1) times.

Therefore, we get the output abcabc, i.e., the string abc gets repeated one time.

```x = 3
y = '4'
result = x*y
print("Result:", result)```

Output

`Result: 444`

If you actually want to multiply numbers and don’t want the repetition, then convert the variable y to an integer using the int() method.

```x = 3
y = '4'
result = x*int(y)
print("Result:", result)```

Output

`Result: 12`

## How to Multiply Variables in Python: Variables of type string or float

Multiplying a string by a string or a floating-point number will cause an error.

```x = 3.2
y = '4'
result = x*y
print("Result:", result)```

Output 1 Output 1 Multiplying Variables in Python

```x = '333'
y = '4'
result = x*y
print("Result:", result)```

Hey I tried copying x = 3.2 y = '4' result = x*y print("Result:", result)

But it says

x = 3.2 y = '4' result = x*y print("Result:", result)
