Convert the string to Double in Python

In this tutorial, we are going to learn about how to convert the string to a double in Python with the help of examples.

Consider, we have the following string in our code:

str = "234.123"

Now, we need to convert the above string "234.123" to a double 234.123.

Using float() function

To convert a string to a double, we can use the built-in float() function in Python.

The float() function takes the string as an argument and converts it to a double.

Here is an example:

str = "234.123"

print(float(str))

Output:

234.123

Similarly, we can use the Decimal() function in Python to convert a string to Double.

Here is an example:

from decimal import Decimal

str = "234.123"
result = Decimal(str)

print(result)
print(type(result))

Output:

234.123
<class 'decimal.Decimal'>

Note: In the above code, we have imported the Decimal() function from the decimal module.
