Convert an integer to a Python string

This post will discuss how to convert an integer to a string in Python.

1. Using String constructor

The standard solution to convert an object to a string is using the str(object) function.

if __name__ == '__main__':

x = 10

s = str(x)

print((s, type(s))) # ('10', <class 'str'>)

The str(object) function internally calls the __str__() function of the object, which returns the object’s string representation.

if __name__ == '__main__':

x = 10

s = x.__str__()

print((s, type(s))) # ('10', <class 'str'>)

2. Using f-strings

Another Pythonic approach is to use the f-string (formatted string literal) starting with Python 3.6. You can do this by prefixing the string literal with f so that the replacement fields within the curly braces {} gets evaluated at the run time.

if __name__ == '__main__':

x = 10

s = f'{x}'

print((s, type(s))) # ('10', <class 'str'>)

3. Using `str.format()` function

Before version 3.6, you can use the str.format() function. Here’s an example of its usage:

if __name__ == '__main__':

x = 10

s = '{}'.format(x)

print((s, type(s))) # ('10', <class 'str'>)
