How to Convert Integer to String in Python

Introduction:

In Python, data conversion is a frequent task, especially when dealing with different data types. Converting an integer to a string might seem straightforward, but understanding the nuances and techniques involved is essential for efficient coding. This comprehensive article takes you through various methods of converting integers to strings in Python, ensuring you’re equipped to handle this common data manipulation task with finesse.

The Need for Conversion

Understand the scenarios where converting an integer to a string becomes necessary, such as formatting output or data manipulation.

Different Options of Conversion

In Python an integer can be converted into string in different ways. In this tutorial, I’ll show you some examples how to convert integer to string in Python. Now let’s see five examples to do it.

Option-1: Using  str() function

intVal=12
print("Variable Type Before conversion : ", type(intVal))
strVal = str(intVal)
print("Variable Type After conversion : ", type(strVal))


Output:

Variable Type Before conversion : <class 'int'>
Variable Type Before conversion : <class 'str'>


Option-2: Using “%s” keyword

intVal = 12
print("Variable Type Before conversion : ", type(intVal))
strVal = "% s" % intVal
print("Variable Type After conversion : ", type(strVal))

Output:

Variable Type Before conversion : <class 'int'>
Variable Type Before conversion : <class 'str'>


Option-3: Using Using {}format

intVal = 12
print("Variable Type Before conversion : ", type(intVal))
strVal = "{}".format(intVal )
print("Variable Type After conversion : ", type(strVal))

Output:

Variable Type Before conversion : <class 'int'>
Variable Type Before conversion : <class 'str'>

Option-4: Using f-string

intVal = 12
print("Variable Type Before conversion : ", type(intVal))
strVal = f'{intVal}'
print("Variable Type After conversion : ", type(strVal))

Output:

Variable Type Before conversion : <class 'int'>
Variable Type Before conversion : <class 'str'>

Option-5: Using __str__() method

intVal = 12
print("Variable Type Before conversion : ", type(intVal))
strVal = intVal.__str__()
print("Variable Type After conversion : ", type(strVal))

Output:

Variable Type Before conversion : <class 'int'>
Variable Type Before conversion : <class 'str'>
