In this tutorial, I will explain how to print strings and integers together in Python. As a developer in the USA, I often need to combine different data types like strings and integers in my Python programs for various applications. Printing them together can be tricky if you’re not familiar with the proper techniques. Let’s get in and explore several methods to solve this common programming task.
Print Strings and Integers Together in Python
Python provides several ways to print strings and integers together in Python. Let us see some important methods.

1. Concatenate Strings and Integers
One way to print strings and integers together is by concatenating them into a single string before printing. However, you can’t directly concatenate a string with an integer using the + operator in Python. You’ll encounter a TypeError. For example:
name = "John"
age = 25
print("My name is " + name + " and I am " + age + " years old.")This will raise a TypeError: can only concatenate str (not "int") to str.
To fix this, you need to convert the integer to a string using the str() function:
name = "John"
age = 25
print("My name is " + name + " and I am " + str(age) + " years old.")Output:
My name is John and I am 25 years old.I have executed the above example code and added the screenshot below.
By converting the integer age to a string using str(age), you can now concatenate it with other strings in the print() function.

2. Use f-Strings (Python 3.6+)
Python 3.6 introduced f-strings, which provide a more concise and readable way to include variables and expressions inside string literals. With f-strings, you can directly embed variables and expressions within curly braces {} inside the string. Python will automatically convert them to strings and include them in the output.
Here’s an example:
name = "Alice"
age = 30
print(f"My name is {name} and I am {age} years old.")Output:
My name is Alice and I am 30 years old.I have executed the above example code and added the screenshot below.
The f prefix before the string indicates that it’s an f-string. The variables name and age are placed inside curly braces {} , and Python will replace them with their respective values during runtime.

3. Use the format() Method
Another approach is to use the format() method, which allows you to insert values into a string template. You can define placeholders using curly braces {} within the string and then provide the values as arguments to the format() method.
Here’s an example:
name = "Michael"
age = 35
print("My name is {} and I am {} years old.".format(name, age))Output:
My name is Michael and I am 35 years old.I have executed the above example code and added the screenshot below.
The placeholders {} act as placeholders for the values that will be inserted. The format() method takes the values as arguments in the order they should be inserted into the placeholders.
You can also use indexed placeholders to specify the order explicitly:
name = "Emily"
age = 28
profession = "software engineer"
print("My name is {0}, I am {1} years old, and I work as a {2}.".format(name, age, profession))Output:
My name is Emily, I am 28 years old, and I work as a software engineer.The numbers inside the placeholders {0}, {1}, and {2} indicate the index of the arguments passed to the format() method.

4. Use the % Operator
Python also supports the % operator for string formatting, similar to the printf() style in C. With this method, you use % placeholders within the string and provide the values as a tuple after the % operator.
Here’s an example:
name = "David"
age = 42
print("My name is %s and I am %d years old." % (name, age))Output:
My name is David and I am 42 years old.The %s placeholder is used for strings, and %d is used for integers. The values are provided as a tuple (name, age) after the % operator.
