Convert Integer to String in Python

Given an integer, the task is to convert it into a string. This is useful when working with text formatting, concatenation or displaying numeric values as strings. For Example:

Input: n = 42
Output: '42'

Let’s explore different methods to convert an integer to a string.

Using str() Function

str() function converts a value into its string representation. It takes the integer as input and returns the equivalent string.

n = 42
s = str(n)

print(s)
print(type(s))

42
<class 'str'>

Explanation: str(n) converts the integer 42 into the string '42' and type(s) confirms that the result is of type str.

Using f-strings

f-strings allow values to be placed directly inside strings using {}. Python automatically converts the integer into a string.

n = 42
s = f"{n}"

print(s)
print(type(s))

42
<class 'str'>

Explanation: {n} inserts the value of n into the string and the integer is automatically converted to a string.

Using format() Function

format() function inserts values into placeholders {} inside a string.

n = 42
s = "{}".format(n)

print(s)
print(type(s))

42
<class 'str'>

Explanation: format() places the integer inside the string placeholder {} and the returned value is a string.

Using %s Formatting

%s placeholder inserts values into a string and automatically converts them to string format.

n = 42
s = "%s" % n

print(s)
print(type(s))

42
<class 'str'>

Explanation: %s acts as a placeholder for the value and Python converts the integer into a string before inserting it.
