Python f-string Tutorial

python f-string tutorial

In this tutorial, you will learn all about python f-string and along with various examples. F-string is a string formatting technique that provides a facility to insert variable values inside a string.
Sometimes we have a large string and we want to insert variables values somewhere inside the string, Then on that time python, f-string plays the most important role.

In this guide, we will see what is f-string in python, syntax, and how to use f-string along with examples.

What is Python f-string?

Python f-string is a string formatting technique to insert variable values inside the string. f-strings in Python is the best way to place variables values inside a string.


Every f-string statement consists of two-part the first is f or F and the next is the string you want to format. A string enclosed between single quote, double-quote, or triple quotes.

Display Variable

To display the variable value inside the string, use curly braces {}. The variables in the curly { } braces are displayed in the output as a normal print statement. Let’s see an example.


name = 'Programming Funda'
type = 'Educational'

a = f'{name} is a {type} website'

Output will be:- Programming Funda is a Educational website

You can use F instead of f but still the output will be the same.

name = 'Programming Funda'
type = 'Educational'

a = F'{name} is a {type} website'


Python f-string also provide a best facility to evaluate expressions inside the string.


a = 12
b = 10
c = 20

print(f"Result will be:- {a + b * c}")

Result will be:- 212

You can also call the function inside the curly braces ( { } ). Let see an example and call function inside the curly braces ( { } ).


#A function to display a simple message
def welcome(name):
	return 'Welcome to ' + name

#Call the function inside f-string	
print(f'{welcome("Programming Funda.")}')

Output will be:- Welcome to Programming Funda.

In the same way, you can also call python built-in function inside the curly braces ( {} ).

mystring = 'programming funda is education blog where you can learn python with fun.'


Programming Funda Is Education Blog Where You Can Learn Python With Fun.

Special Characters

If you want to display special characters like {},\’,\”, which are internally used by python for special meaning. You can use escape characters inside the Python f-string.


If you want to display quotation marks like single, double, or triple then we need to use the escape character to print quotation marks.
Suppose we want to display Welcome to ‘Programming Funda’.

name = "Programming Funda"
print(f"Welcome to \'{ name }\'")

Output will be:- Welcome to ‘Programming Funda’

You can also use double quotation instead of single quotation but still output will be same.

name = "Programming Funda"
print(f"Welcome to \"{ name }\"")

Output will be:- Welcome to “Programming Funda”

Let’s see other type of quotation in python f-string.

print(f'{"Hello, Programming Funda"}')
print(f"{'Hello, Programming Funda'}")
print(f"\"{'Hello, Programming Funda'}\"")
print(f"\'{'Hello, Programming Funda'}\'")


Hello, Programming Funda
Hello, Programming Funda
"Hello, Programming Funda"
'Hello, Programming Funda'


Sometimes we need to print braces in string then we need to use double braces.

mystring  = 'Programming Funda' 
print(f"{{{mystring}}} funda is education blog.")

Output will be:- {Programming Funda} is education blog.


You can access python dictionary item inside curly braces ( {} ).


Student = {

'Name': 'Vishvajit',
'Course': 'BCA',
'Occupation': 'Software Engineer'

print(f"My name is {Student['Name']} Rao, I am a {Student['Occupation']}. I have completed {Student['Course']}.")


My name is Vishvajit Rao, I am a Software Engineer. I have completed BCA.


In this tutorial, you have learned all about Python f-string along with various examples. f-string in python is mostly used by python programmers to insert variables values inside a string. Personally f-string in python mostly used by me to string formatting.
