In Python, single-line comments can be created by adding a hash symbol (#) at the beginning of the line. For example:
# This is a single-line comment
Multi-line comments can be created using triple quotes, either single or double quotes. For example:
"""
This is a multi-line comment
It can span across multiple lines
"""
Alternatively, you can also use the hash symbol (#) at the beginning of each line to create a multi-line comment. For example:
# This is a multi-line comment
# It can also span across multiple lines
Escape sequence characters are used to include special characters in strings. An escape sequence is a backslash () followed by a character that represents a special character. Here are some commonly used escape sequence characters in Python:
\ncreates a new line\tcreates a tab space\'inserts a single quote in a string\"inserts a double quote in a string\\inserts a backslash in a string
For example:
print("This is a string with a\nnew line")
print("This is a string with a\ttab space")
print("This is a string with a single quote: \'")
print("This is a string with a double quote: \"")
print("This is a string with a backslash: \\")
The output will be:
This is a string with a
new line
This is a string with a tab space
This is a string with a single quote: '
This is a string with a double quote: "
This is a string with a backslash: \
In summary, comments and escape sequence characters are important tools for writing clear and readable code in Python. By using comments to explain the purpose of the code and escape sequence characters to include special characters in strings, programmers can make their code more understandable and efficient.
