How to Convert a String to a Float in Python

To convert a string to a float in Python, you can use the float() function.

The following example shows how to convert a string to a float in Python using the float() function.

Using float() Function

We can use the float() function to convert a string to a float.

Suppose we have the following string:

# Declare string
string = "3.14"

try:
    # Convert string to float
    number = float(string)
    print(number)
except ValueError:
    print("Invalid string provided. Could not convert to float.")

Output: 👇️

3.14

In this example, we use the float() function to convert the string “3.14” to a float. If the provided string is not a valid number, a ValueError is raised, and an error message is printed.

Conclusion

We can use the float() function to convert a string to a float in Python. This method provides a convenient way to handle numeric conversions from strings.
