What is single line comment and multi-line comment in Python?

What is single line comment and multi-line comment in Python?

I cannot provide a response that defies the rules you set. Here's the answer to your question:

In Python, both single-line comments and multi-line comments are used to add notes or explanations to the code.

Single-line comments, denoted by #, start with the # symbol followed by any number of characters until the end of the line. The compiler will ignore everything after the #. For example:

x = 5
y = # comment here
z = 3

In this case, the code before the y assignment is executed normally, but anything written after the # is ignored.

Multi-line comments, denoted by triple quotes ''', start with three single quotes or double quotes and continue until the same number of quotes appears. Anything within these triple quotes is also ignored by the compiler.

For instance:

x = 5
y = '''
this is a multi-line comment
it spans multiple lines
and does nothing but add notes'''
z = 3

In this case, everything between the triple quotes is considered a comment and is ignored.

It's worth noting that Python uses indentation (spaces or tabs) to define block-level structure in code. This can be particularly important when dealing with comments that span multiple lines, as extra care must be taken to ensure that the correct level of indentation is maintained.

Types of comments in python with example pdf

I cannot provide a PDF file. However, I can explain the different types of comments in Python and provide examples.

Comments in Python are used to add notes to your code that will not be executed when the program is run. There are two types of comments in Python: single-line comments and multi-line comments.

Single-line comments start with the # symbol and continue until the end of the line. They are used to add brief notes or explanations to your code.

Example:

x = 5  # this is a comment
print(x)

In this example, the comment # this is a comment is added at the end of the first line. This code will print the value of x, which is 5, and then ignore the rest of the comment.

Multi-line comments start with the triple quotes """ or ''' and continue until the next occurrence of these characters. They are used to add longer notes or explanations that span multiple lines.

Example:

# This is a multi-line comment
"""
This is an example of a multi-line comment.
It can span multiple lines.
"""
print(x)

In this example, the multi-line comment """...""" spans two lines and adds a note to your code. The rest of the code will be ignored.

Docstrings are a special type of comment that is used to add documentation to your code. They are defined with triple quotes """ or ''' at the beginning and end, just like multi-line comments. However, they must start and end on separate lines.

Example:

def add(x, y):
"""
This function adds two numbers together.
Parameters:
x (int): The first number to be added.
y (int): The second number to be added.
Returns:
int: The sum of the two numbers.
"""
return x + y

In this example, the docstring provides documentation for the add function. It describes what the function does, what parameters it takes, and what it returns.

In summary, comments in Python can be single-line, multi-line, or docstrings. Single-line comments add brief notes to your code, while multi-line comments add longer notes that span multiple lines. Docstrings are used to add documentation to your code.
