Convert integer to string in Python
In Python an integer can be converted into a string using the built-in str() function. The str() function takes in any python data type and converts it into a string. But use of the str() is not the only way to do so. This type of conversion can also be done using the “%s” keyword, the .format function or using f-string function.
Below is the list of possible ways to convert an integer to string in python:
1. Using str() function
Syntax: str(integer_value)
Example:
Python3
num = 10 # check and print type of num variable print ( "Type of variable before conversion : " , type (num)) # convert the num into string converted_num = str (num) # check and print type converted_num variable print ( "Type After conversion : " , type (converted_num)) |
Output:
Type of variable before conversion : <class 'int'> Type After conversion : <class 'str'>
2. Using “%s” keyword
Syntax: “%s” % integer
Example:
Python3
num = 10 # check and print type of num variable print ( "Type of variable before conversion : " , type (num)) # convert the num into string and print converted_num = "% s" % num print ( "Type after conversion : " , type (converted_num)) |
Output:
Type of variable before conversion : <class 'int'> Type after conversion : <class 'str'>
3. Using .format() function
Syntax: ‘{}’.format(integer)
Example:
Python3
num = 10 # check and print type of num variable print ( "Type before conversion : " , type (num)) # convert the num into string and print converted_num = "{}" . format (num) print ( "Type after conversion :" , type (converted_num)) |
Output:
Type before conversion : <class 'int'> Type after conversion : <class 'str'>
4. Using f-string
Syntax: f'{integer}’
Example:
Python3
num = 10 # check and print type of num variable print ( "Type before conversion : " , type (num)) # convert the num into string converted_num = f '{num}' # print type of converted_num print ( "Type after conversion : " , type (converted_num)) |
Output:
Type before conversion : <class 'int'> Type after conversion : <class 'str'>
5. Using __str__() method
Syntax: Integer.__str__()
Python3
num = 10 # check and print type of num variable print ( "Type before conversion : " , type (num)) # convert the num into string converted_num = num.__str__() # print type of converted_num print ( "Type after conversion : " , type (converted_num)) |
Output:
Type before conversion : <class 'int'> Type after conversion : <class 'str'>
