You can multiply two numbers together in Python . You can also multiply a number by a string. This returns a sequence of a string that repeats a specific number of times.

If you try to multiply one string by another string, you will encounter the error " TypeError: unable to multiply sequence for non -int of type ’str’" error.

In this guide, we explain what this error means and where you might encounter it in your code. Let’s look at an example of this error to help you understand how to fix it.

## TypeError: Cannot multiply sequence by non-int of type ’str’

Strings are a type of sequence . This is because they contain characters that Python can iterate over. Other types of sequences include tuples, dictionaries, and lists.

Use the multiplication operator (*) to create a string that repeats the contents of a string. Consider the following code:

This code returns: "Cakes! Cakes! ". The multiplication operator causes our string to repeat twice.

You cannot use the multiplication operator to multiply a string by a string. Integers and numbers to Floating point are the only values ‚Äã‚Äãthat can be multiplied by values ‚Äã‚Äãof the same data type. Python has no way of interpreting the multiplication of two strings.

## An example scenario

Let’s create a program that calculates how much money a restaurant made from their jam scones on a Thursday afternoon.

To begin with, we need to set the price of a jam scone. We also ask that you tell us how many jam scones you sold in the last day of operation using an ’ input () :

Next, let’s multiply those two values ‚Äã‚Äãtogether. This will tell us how much money was made with jam scones on a given day:

Now that we know how much the scones have won, let’s write a `print ()` statement that informs the user of the result of our calculation:

The format () method allows us to add the value of "earned_from_scones" where our braces ({}) appear in our string.

We also need to calculate how much profit is made on each muffin. We know we make 25 cents on every muffin. To calculate how much profit is made, we use this code:

This code calculates the profit made on each muffin, then prints that value to the console. Let’s run our code and see if it works:

Our code returns an error.

Let’s analyze the line of code of our error:

Although this li gne code looks correct, there is a problem: we are trying to multiply two string values ‚Äã‚Äãtogether. We store "jam_scone" as a string. The `input ()` method returns a string, which means that `sold ()` has a string value.

To solve this problem, we need to make sure that " jam_scone " and " sold " are floating points. This allows us to perform a mathematical operation on these values.

Next, let’s change the way we declare the values ‚Äã‚Äãof these variables:

The value of" jam_scone " is no longer in quotes . This shows that we have changed "jam_scone" from a string to a float. We also used the float () method to convert the "sold" value to a floating point number.

Run our code and see what happens:

Our code is working fine. First, our code asks the user to enter how many scones are sold in the console. Then our program calculates how much money the store has made selling scones. Finally, our program calculates the profits generated by sales of scone.

## Conclusion

The error " TypeError: cannot multiply the sequence by the non-integer of type ’str’ ’occurs if you try to multiply the values ‚Äã‚Äãof two strings together. You can solve this problem by making sure to multiply two numeric values ‚Äã‚Äãtogether or just multiply a string by an integer.

You are now ready to resolve this error as a Pythonist!
