How Does Java Read Multi Line Comments

Introduction to Python Multiline Comment

It has been in practice for decades for the developers to add together comments in the program in guild to provide instructions on what the particular block of code is supposed to be doing when executed. In python, only unmarried-line comments are accepted, which tin can be done using '#'. For making a multiline comment, one can declare whatever symbol like declaring a variable in a function and telephone call the function for entering plain text wherever it is required in the programme.

How Python Multiline Comment Works?

Comments in the programme are a set of words meant to help users understand the plan in the English language, which is easily readable. In python, the hash character (#) is used at the start of the line to brand information technology a annotate. There is no multiline comment in Python, but still, at that place is a practice of using triple quotes for declaring multiline comments.

It is important to see the alignment every bit in Python; the indentation works instead of placing curly braces for defining a function. And so while writing the comments, nosotros should exist careful about indentation. For example, you might add a note before the function torso just inside the office, which is also known equally docstring, similar to multi-line comments that don't have any indentation. Merely the role could have blocks of lawmaking indented at multiple levels. So the need for comment indentation besides equally role blocks is necessary to be indented properly.

Let u.s. come across how to indicate unmarried line comments in Python with the below instance:

Code:

# Program to print the statement
print "How-do-you-do Educba"

Output:

The blue color words starting with a # character in the comment line in the higher up program. And below is the program code to impress the statement. This is a single-line comment that starts with the hash character (#) and ends with the line'southward end. These single-line comments are used for brusk and quick notes to annotate on the understanding of the plan.

Multiline Comments in Python with Example

Multiline comments are incorrect to use in Python because if there are any number of lines to annotate they should start with a hash character (#) followed by one infinite for each line. Allow us see in below instance:

Case #1

Code:

# To larn how to utilise comments
# Python does non have any special symbol for multiline comments.
# Program to print the statement
print "Hello Educba"

Output:

Explanation: From the above example, at that place are 3 comment lines that are blueish in color, therefore the python hash character (#) is used for both unmarried and multiline comments, but in a multiline annotate, hash graphic symbol (#) is followed past infinite for declaring information technology as a multi-line annotate.

Instance #2

In some practices in Python, multiline comments are indicated using triple quotes (" " " " " "). In Python, even docstring is also divers in triple quotes, but docstrings are usually defined inside a form, function, module, or method as a first argument. This docstring may appear as a multiline annotate, then Python does not support multiline comment due to this ambivalence between multiline comment and docstring. As python compiler ignores the annotate while executing the program, simply in the case of the docstring, you lot can access them with the special variable myobj.doctor.

Lawmaking:

'''
To acquire how to employ comments
Python does not accept whatsoever special symbol for multiline comments.
Program to print the argument
'''
print "Hello Educba"

Output:

Explanation: In the to a higher place example, which describes the apply of multiline comments, which is described within triple quotes. Beneath is the screenshot that shows the instance for multiline, which is in dark-green in color.

Instance #3

In Python, multiline comments are not supported because of docstring, which coincides with the multiline comment equally the compiler considers them as they are described inside function or course or modules. Docstring is not a comment; they are a python string documentation feature that allows adding quick notes inside a role, course, or module.

Code:

def docFunction():
'''
This function is an example of docstring in Python.
'''
print("Python docstrings are not multiline comments.")
print("\ndocstring value...")
print(docFunction.__doc__)

Output:

Caption: The above example is for how to declare docstring, which is similar to multiline comment. In Python, every bit the comment is declared using the hash character for the single line and multiline, the practice for multiline comment is usually declared using triple quotes. Therefore always declare in the proper way of comments or docstring as they atomic number 82 to quicker execution of the program as well equally an easy understanding of the code for users.

Conclusion

In Python, comments are written to make users understand the program code or in readable code. Python does not support multiline comments every bit there is an ambivalence between comment and docstring. As both multiline and docstring are declared inside the triple quotes (" " " " " "). In python, comments are declared starting with the hash character (#) and catastrophe with EOL ( End of the line). Thus equally docstring can be declared within triple quotes but within the function or module or method or class, which is similar to the multiline comment.
