Definition of Python Object to StringPython object in python refers to the object which is used by the other functions in order to get the direct conversion of one data type present within the object into another data type present in the other object. Python is all about objects thus the objects can be directly converted into strings using methods like str() and repr(). Str() method is used for the conversion of all built-in objects into strings. Similarly, repr() method as part of object conversion method is also used to convert an object back to a string. Syntax: Initialize an object first :
Need to perform Typecasting in order to get the object for converting into a string.
Need to print the object for getting the details about the data type present within the object.
Need to make the final casting into object_strng for getting the final value of string.
How to Convert Object to String in Python?There are ways to convert object into string in Python with some of the rules and regulations. The working flow includes many of the constraints as mentioned:
ExamplesLet us discuss examples of Python Object to String. Example #1This program demonstrates the conversion of a variable being assigned with an integer directly into the string type object as shown. With an error which says that if in case the variable assigned includes text will result in a type error. Code:
Output: Note: Since the variable is an integer it is accepting the value and converting it to string with the print function otherwise if by any instance some extra variable is added with the variable then it will throw error as : can only concatenate str not int to str Example #2This program demonstrates the code where if we incorporate the string with an object and then perform a typecast it will return the required string from the object defined as shown in the output. Code:
Output: Example #3This program demonstrates the conversion of object to string using str() method as shown in the output. Code:
Output: Example #4This program demonstrates the conversion of a class Object into a String with memory address and assignment of object with object name as shown in the output but still, it needs to get converted by typecasting it into a proper object. Code:
Output: Example #5This program demonstrates the conversion of object to string and based on that overloading of the string function is performed as shown in the output. Code:
Output: Example #6This program demonstrates the repr() method for conversion of an object to string as shown in the output. Mostly it will contain complex and custom objects to be decoded into string. Code:
Output: ConclusionA conclusion can be made with the fact that objects in python play a vital role as it contains all the necessary information regarding the class and once decoded gives the string format of the entire details which gives an overview about the actual class and its implementation. Str() method in python plays an important role whenever it is needed to be retrieved with the value. Recommended ArticlesThis is a guide to Python Object to String.

Can you convert object to string?We can convert Object to String in java using toString() method of Object class or String. valueOf(object) method. You can convert any object to String in java whether it is user-defined class, StringBuilder, StringBuffer or anything else. Which function is used to convert an object to a string in Python?The answer is option D (str(x)). str(x) converts the object to a string in python. How do you change an object to text?Use the JavaScript function JSON. stringify() to convert it into a string. const myJSON = JSON. stringify(obj); What is __ str __ in Python?Python __str__() This method returns the string representation of the object. This method is called when print() or str() function is invoked on an object. This method must return the String object. |
