lcd module python code quotation
Spanning strings over multiple lines can be done using python’s triple quotes. It can also be used for long comments in code. Special characters like TABs, verbatim or NEWLINEs can also be used within the triple quotes. As the name suggests its syntax consists of three consecutive single or double-quotes.Syntax: “”” string””” or ”’ string”’
Note: Triple quotes, according to official Python documentation are docstrings, or multi-line docstrings and are not considered comments.Anything inside triple quotes is read by the interpreter. When the interpreter encounters the hash symbol, it ignores everything after that. That is what a comment is defined to be.
Another use case of triple quotes is to create strings in Python. Adding the required characters within triple quotes can convert those characters into python strings. The below codes shows the use of triple quotes for creating strings:
A computer program looks like a code language, which is necessary for the computer to precisely understand what your commands mean. But, being a code language makes it harder for humans to read. To compensate for this, you are allowed to write extra notes in your program that the computer ignores. These notes are called comments.
In Python, any line of instructions containing the # symbol ("pound sign" or "hash") denotes the start of a comment. The rest of the line will be ignored when the program is run. Here is an example.
Because the second line started with a # sign, Python totally ignored that line, and as you can see, the number 2 was not printed. Common uses for comments include:
Here is an exercise to illustrate. If you edit the code too much and want to bring back the default version of the code, select Reset code to default.
What if you want to include the quote character " inside of a string? If you try to execute print("I said "Wow!" to him") this causes an error: the problem is that Python sees one string "I said " followed by something Wow! which is not in the string. This is not what we intended!
You can put a backslash character followed by a quote (\" or \"). This is called an escape sequence and Python will remove the backslash, and put just the quote in the string. Here is an example.
As stated in earlier tutorials, the print() function tells Python to immediately display a given string once the command is executed. To designate a string for the print function to display, surround it in either single-quotes (" ") or double-quotes (" "). Both options are available so you can still use quotes within your string if need be. Ex: print("how are you doin" today?")
If the pound symbol (#) is placed before a command or any sort of string of characters, the command will appear in red and Python will ignore it during code execution. This can be used within Python to provide helpful comments to those looking at your code, or to "turn off" certain lines of code in order to test for bugs.
Surrounding a string with triple double-quotes (""" """) allows you to have any combination of quotes and line breaks within a string and Python will still interpret it as a single entity.
In Python strings, the backslash "\" is a special character, also called the "escape" character. It is used in representing certain whitespace characters: "\t" is a tab, "\n" is a newline, and "\r" is a carriage return.
You can call out code or a command within a sentence with single backticks. The text within the backticks will not be formatted. You can also press the Command+E (Mac) or Ctrl+E (Windows/Linux) keyboard shortcut to insert the backticks for a code block within a line of Markdown.
If you are frequently editing code snippets and tables, you may benefit from enabling a fixed-width font in all comment fields on GitHub. For more information, see "Enabling fixed-width fonts in the editor."
To create a nested list using the web editor on GitHub or a text editor that uses a monospaced font, like Visual Studio Code, you can align your list visually. Type space characters in front of your nested list item, until the list marker character (- or *) lies directly below the first character of the text in the item above it.
Python accepts single ("), double (") and triple (""" or """) quotes to denote string literals, as long as the same type of quote starts and ends the string.
