ASCII Control Characters

Alright, ASCII control characters those mysterious little guys that make your computer go “beep” when you press them on your keyboard. But before we dive into this exciting topic, let me just say: if you’re not a total nerd like us, you probably don’t care much about these things.

So why should you even bother learning about ASCII control characters? Well, for starters, they can be pretty useful in certain situations especially when it comes to automating tasks or manipulating text files. And hey, who doesn’t love a good geeky challenge every now and then?

But before we get into the details of ASCII control characters, let me first explain what they are (in case you somehow missed this in your computer science classes). Essentially, these characters are not meant to be displayed on screen or printed out instead, they’re used for controlling various aspects of a text file or terminal window.

For example, the “backspace” character (ASCII code 08) is often represented by the backslash followed by b (i.e., “\b”) in Python strings. This can be useful if you want to delete the previous character without actually pressing the backspace key on your keyboard which can come in handy when writing scripts or automating tasks that involve text manipulation.

Another popular ASCII control character is the “newline” (ASCII code 0A), which is represented by “\n” in Python strings. This is often used to create a new line of text, and can be especially useful when writing scripts or automating tasks that involve printing out large amounts of data.

But wait there’s more! Did you know that the “tab” character (ASCII code 09) can also be represented by “\t” in Python strings? This is often used to create a tab space between columns of text, and can come in handy when writing scripts or automating tasks that involve formatting data.

Of course, there are many other ASCII control characters out there some more useful than others (like the “bell” character, which makes your computer beep). But for our purposes today, we’ll stick to the basics and focus on those three: backspace, newline, and tab.

So how can you use these ASCII control characters in Python? Well, it’s actually pretty simple just add them to your strings using their corresponding escape sequences (i.e., “\b”, “\n”, or “\t”). Here are a few examples:

# This script demonstrates how to use ASCII control characters in Python strings.

# The backspace character ("\b") deletes the character before it in a string.
print("Hello\bworld") # prints "Helloworld" with the first 'l' deleted

# The newline character ("\n") creates a new line in a string.
print("This is a test.\nThis is another line.") # prints "This is a test." followed by a newline and then "This is another line."

# The tab character ("\t") adds a tab space in a string.
print("Column 1\tColumn 2") # prints "Column 1" followed by a tab space, and then "Column 2"

And there you have it the basics of ASCII control characters in Python. Of course, this is just scratching the surface there are many other useful escape sequences out there that can help you automate tasks or manipulate text files. But for now, let’s stick to these three and enjoy the simple pleasures of geeky programming!

But wait a minute… what about those special symbols we mentioned earlier? Can we use them in Python strings as well? The answer is yes all capital (A-Z) and small (a-z) alphabets, digits 0-9, and special symbols like l ; : ! are supported by Python.

So let’s say you want to print out a string that includes an apostrophe or a semicolon no problem! Just add them directly into your string using their corresponding characters:

# The following script prints a string that includes an apostrophe and a semicolon.

# The print() function is used to display the specified content on the screen.
# The string is enclosed in double quotes to indicate that it is a string.

print("Don't forget the 'quotes' and ;semicolons;") # prints "Don't forget the 'quotes' and ;semicolons;"

# The string contains both single and double quotes, which are used to indicate the beginning and end of a string.
# The semicolons are included directly in the string using their corresponding characters.

And that’s it! You now have a basic understanding of ASCII control characters in Python, as well as how to use them alongside other special symbols.
