+Fstring is a cool feature introduced as a part of Python 3.6. Fstring can be
+elaborated as "Formatted String". At the time of writing this post, Python
+already has more than two ways to a format string. Still, Fstring is released by
+giving yet another way to format a string. Fstrings can be easy to understand
+and simple to read. When you prefix the string with ```f```, it becomes a
+formatted string. All names wrapped inside the curly braces ({}) are resolved
+with the value of variable available in local scope. If the variable isn’t found
+in the local scope then it will raise a ```NameError``` exception.
+
+
+### Demonstration

+
+Below is the code used in the example
+
+```python
+name = "Jay"
+print(f"Hello {name}")
+```
+
+[ TODO: Find, Are there any tool avilable to convert all a formatted strings to
+Fstrings?]
+
+In my view, this option of string formation is more concise and readable than
+all other options. I advise migrating your code to Fstrings if your Python
+interpreter is greater than or equal to version 3.6. You should note that
+existing string formation approaches are still supported and are not subject to
+depreciate in the near future.
+
+
+### Summary
+
+
+* Fstring can be elaborated as "Formatted String".
+
+* Variable is always resolved at local scope. If it isn't found then it will
+  rise the ```NameError``` exception.
+
+* You can format your strings by Fstring approach only if your Python
+  interpreter version is greater than or equal to 3.6.
+
+* Existing string formation approches are not subjected to depricate soon.
