Python repr() function

The repr() function in Python returns the canonical string representation of an object. For example:

x = 'Python Programming'
print(repr(x))
x = [1, 2, 34, 43]
print(repr(x))

The output will be:

'Python Programming'
[1, 2, 34, 43]

Python repr() function syntax

The syntax of the repr() function in Python is:

repr(object)

The repr() function basically returns the printable representation of an object.

Note: For many types of objects, including the most built-ins, eval(repr(obj)) gives obj.

Python repr() function example

Here is an example of the repr() function in Python:

print("Enter the string: ", end="")
str = input()

print("\n----The string is, without repr(str)----")
print(str)
print("\n----The string is, with repr(str)----")
print(repr(str))

The snapshot given below shows the sample run of the above program, with user input codes cracker dot com as a string:

Note: The repr() method is used to print the official representation of an object.

Advantages of the repr() function in Python

• Gives you a string representation of an object that you can use to recreate it later.
• The repr() function represents an object in a clear and unambiguous manner, making it useful for debugging and testing.
• Some built-in Python functions, such as eval(), use it to recreate objects.

Disadvantages of the repr() function in Python

• The string representation returned by repr() is not always user-friendly and may contain a lot of technical detail that the user is not interested in.
• The string representation returned by repr() can be difficult to read and understand if the object being represented is large or complex.
• Some Python objects may lack a meaningful repr() representation or may have a repr() representation that is unsuitable for use in recreating the object.
