Java’s built-in toString () function returns the provided value in string format. Any object to which this method applies will convert into a string item that serves as the return value. This technique has thrived in Java for decades, and a burning inquiry has arisen: what is toString () equivalent in Python? 

Our straightforward guideline will shed some light on this mystery. Keep scrolling!

What Is toString () Equivalent in Python? 

str() is the Python counterpart of Java’s toString() function, which plays a critical role in Python-operated programs by transforming different-type objects into a string. Upon application, it internally invokes the __str__() operation to yield a string representation of this object.

The following is a pretty simple example:

Codes:

x = 28
l1 = [19,28,22]
s_l1 = str(l1)
s_x = str(x)
print(s_x, type(s_x))
print(s_l1, type(s_l1))

Output:

28 <class 'str'>
[19, 28, 22] <class 'str'>

What Are The str() Parameters?

This algorithm involves three parameters:

Object: The object for which the string representation will get returned. If not specified, the system gives an empty string. 

Encoding: The object’s encoding. Defaults to UTF-8 if not stated.

Errors: The response sent after decoding failures. The default is set to ‘strict’.

Aside from that, there are six missteps categories:

Strict: The default answer that throws a UnicodeDecodeError exceptional case failure

Ignore: The omission of the non-codable Unicode from the output replace. It substitutes the unencodable Unicode with a question mark.

Xmlcharrefreplace:  This category employs an XML character reference rather than an unencodable Unicode

Backslashreplace – The program replaces unencodable Unicode with an uNNNN espace sequence

Namereplace: It appends a \N {…} escapade sequence in place of the unencodable input. 

Take a look at this illustration:

Codes:

# Python program to demonstrate

# str()
x = bytes("\nIttutoria.net", encoding = 'utf-8')
s = str(x, encoding = "ascii", errors ="ignore")
print(s)

Output:

Ittutoria.net

The character Z should generate an alert as ASCII cannot decipher it. However, this issue is entirely disregarded since the errors are set to ‘ignore’.

How Does It Operate with Bytes?

If coding and error parameters are supplied, the object argument should be a bytes-like object (bytearray or bytes).

Suppose the object type is byterarray or bytes. The str() will cue bytes.decode (encoding, errors). Otherwise, the bytes item will get placed in the buffers before the decode() function is called.

Code:

# with bytes

y = bytes('Itutöria.net', encoding='utf-8')
print(str(y, encoding='ascii', errors='ignore'))

Output:

Itutria.net

FAQs

1. How Can I Include A Character in A String?

There are four possible approaches:

• Using join()
• Using %
• Use format()
• Using f-strings

2. How Can I Verify That A Pair of Strings Are Identical?

The “is” operator produces “True” if two names refer to the same memory location. Do not mistake “is” with ==, which only validates equality.

birds           = ['falcon', 'sparrow', 'flamingo']
more_birds      = birds
print(birds == more_birds)
print(birds is more_birds)
even_more_birds = ['falcon','sparrow']
print(birds == even_more_birds)
print(birds is even_more_birds)

Output

True
True
False
False
