How To Add Float And String In Python

In this tutorial, you will learn how to add float and string in Python. This can help you when performing mathematical operations or data manipulation involving different types of data, such as floats and strings. By following the steps provided, you will learn how to convert a string to a float, then add it to another float.

Step 1: Understand Floats and Strings

Before we start, here’s a brief explanation of floats and strings in Python.

  • Float: A float is a floating-point number that can store a real number, like 3.14, 0.01, or -56.73. Floats are essential when you need to work with decimal numbers in calculations.

  • String: A string is a sequence of characters, like “hello,” “3.14,” or “abc123.” Strings are enclosed in single or double quotes and can store text, numbers, or special characters.

Step 2: Converting String to Float

To add a float and a string together, you need to convert the string to a float first. You can do this using the float() function. As an example, suppose you have the following float and string:

You can convert the string, num_string, into a float like this:

Step 3: Adding Float and Converted String

After converting the string to a float, you can add the two numbers together. Using our example, we can add num_float and our newly converted string, converted_string:

Step 4: Displaying the Result

Finally, you can print the result of the addition using the print() function.

The expected output of our example would be:
