Python str
Python str() builtin function is used to create a string from a Python object, or a Python bytes object with an optionally specified encoding and error handling action.
In this tutorial, we will learn about the syntax of Python str() function, and learn how to use this function with the help of examples.
Syntax
The syntax of str() function with a Python object as parameter is
str(object='')
where
| Parameter | Required/Optional | Description |
|---|---|---|
| object | Optional | A python object. The default value is empty string. |
The syntax of str() function with a Python bytes object, encoding and errors as parameters is
str(object=b'', encoding='utf-8', errors='strict')
where
| Parameter | Required/Optional | Description |
|---|---|---|
| object | Optional | A python bytes object. |
| encoding | Optional | Encoding of data in given object.Possible Values – ascii, big5, utf_8, utf_16, utf_32, or etc. |
| errors | Optional | The handling that has to happen when an error occurs while decoding given object using given encoding standard.Possible Values – strict, ignore, replace, xmlcharrefreplace, backslashreplace, namereplace, or surrogateescape. |
Returns
The function returns string object.
Examples
1 strobject
In this example, we will create a string from list object. Take a list initialized with some elements, and pass this list as argument to str() builtin function.
Python Program
myList = [2, 4, 6, 8] myString = str(myList) print(myString)
Output
[2, 4, 6, 8]
[2, 4, 6, 8] in the output is a string object.
2 strobject, encoding
In this example, we will create a string from bytes object with specific encoding.
Python Program
object = b'\x61\x00\x62\x00\x63\x00\x64\x00' myString = str(object, encoding='utf-16') print(myString)
Output
abcd
Conclusion
In this Python Tutorial, we have learnt the syntax of Python str() builtin function, and also learned how to use this function, with the help of Python example programs.
