Python is one of the most popular programming languages used in engineering, data analytics, and machine learning. Python is a high-level programming language that is easy to use and read. It has numerous libraries and packages for development. 

This blog will help you learn how to convert String to Double in Python. Without wasting your time, we will explain it in the shortcoming paragraph.

How to convert String to Double in Python

There are two ways to turn a string into a double. The first method is by using float(), and the second is by using decimal() to transform a string into a double (). Any of the methods can be used to turn a string into a double. So let’s learn more about this without wasting any more time. We will explain it further by applying the following examples.

from decimal import Decimal string = '1974.6323' vab1 = Decimal(string) print(vab1) 

Output : 1974.6323

string = '1974.6323' vab1 = float(string) print(vab1) 

Output : 1974.6323

Method 1: using float()

You may quickly convert String to Double in Python by float().

The floating-point number or float type is returned by the float() function, which accepts an integer or string as input. You can send a string to the float() function to change it into a float. The example code that follows shows how to use the float() method to change a string into a float (double-precision number).

string = '1974.6323' 
vab1 = float(string) 
print(vab1)

And its output.

1974.6323

Python lacks a specified “double” file format. However, it offers the float format, which performs and has the same accuracy as doubles in other applications. In Python, apply the built-in method float to transform a string with numbers to a “double”.

For instance, the phrase float(‘123.456’) outputs the float value 123.456.

Method 2: using decimal()

Another way of converting String to Double in Python is using decimal().

The initialization decimal() method of module’s Decimal accepts the input of numeric value and changes it into a decimal type that can precisely store and represent all numeric values and have as much accuracy as required. You can use the decimal() method to get a decimal type variable by passing it the string that has to be transformed into a double-precision number. Python’s decimal() method can be used to transform a string into a double-precision number. An example of the code is provided below.

from decimal import Decimal 
string = '1974.6323'. 
vab1 = Decimal(string) 
print(vab1)

The output of it will be as follows.

1974.6323

Conclusion

You may apply our methods while understanding how to convert String to Double in Python. In our blog post, we suggested applying decimal() or float(). Or you may apply your solution, as long as it is effective.
