Convert integer to string in Python

In this article, we’ll explore different methods for converting an integer to a string in Python. The most straightforward approach is using the str() function.

Using str() Function

str() function is the simplest and most commonly used method to convert an integer to a string.

n = 42

s = str(n)
print(s)

42

Explanation: str(n) converts n to a string, resulting in ‘42‘.

Using f-strings

For Python 3.6 or later, f-strings provide a quick way to format and convert values.

n = 42

s = f"{n}"
print(s)

42

Explanation: The {n} inside the f-string automatically converts n to a string.

Using format() Function

format() function inserts values into {} placeholders in a string. This is similar to f-strings but works with older versions of Python (before 3.6).

n = 42

s = "{}".format(n)
print(s)

42

Explanation: format() places n into {}, converting it to ‘42‘

Using %s Keyword

The %s keyword allows us to insert an integer (or any other data type) into a string. This method is part of the older style of string formatting but still works in Python.

n = 42

s = "%s" % n
print(s)

42

Explanation: The %s keyword acts as a placeholder within the string and automatically converts n to a string before inserting it in place of %s. This approach can be useful for quick formatting but is less commonly used than f-strings or format().

Using repr() for Debugging

repr() function is usually used for debugging, as it gives a detailed string version of an object. While it also converts integers to strings, it’s not the most common method for simple integer-to-string conversion.

n = 42

s = repr(n)
print(s)

42

Explanation: repr(n) returns a string ‘42‘. It’s similar to str() but usually used for debugging.
