 A User – is any person that interacts (by inputs) with a program without having to write the code directly. For example, you are the user to the code that makes your browser/website run. When you clicked on this pop-up, that was the input that made this explanation come up when the code detected it.

  • varName.istitle() – Returns True if the string follows the rules of a title.
  • varName.ljust(value) – Returns a left justified version of the string.
  • varName.rjust() Returns a right justified version of the string.

  • varName.upper() – Converts a string into upper case.
  • varName.strip() – Returns a trimmed version of the string.
  • varName.lstrip() – Returns a left trim version of the string.
  • varName.rstrip() Returns a right trim version of the string.
  • varName.partition() – Returns a tuple where the string is parted into three parts.
  • varName.replace(“old”, “new”) – Returns a string where a specified value is replaced with a specified value.
  • varName.rfind() – Searches the string for a specified value and returns the last position of where it was found.
  • varName.rindex() – Searches the string for a specified value and returns the last position of where it was found.
  • varName.rpartition() – Returns a tuple where the string is parted into three parts.

String Special Characters

There a number of special string characters that have different functions when used inside ” “. Here’re some useful and common ones:

  • \n – Newline – Everything after it goes to next line.
  • \t – Horizontal tab – creates a tab space, similar to when you use ‘tab’ on keyboard.
  • \b – backspace – deletes the character before the it.
  • \r – carriage return – same as \n

In programming Concatenation is a process of appending one string to another. 

\ – escape character is a string character that tell Python that the next character after it should be taken as a string and not as an instruction.

str ( ) is a built-in function that converts and sequence of characters (numbers especially) in to text. 

Mad Libs is a phrasal template word game created by Leonard Stern and Roger Price. It consists of one player prompting others for a list of words to substitute for blanks in a story before reading aloud.

type ( ) is a built-in function (still to cover what built-in functions are later) that determines the Data Type of any data presented. 

input ( ) is a built-in function (still to cover what built-in functions are later) allows a user to insert info into a program/the code. 

print ( ) is a built-in function (still to cover what built-in functions are later) that executes data inside the brackets. The results get printed out on the console/results section.

Integrated Development Environment (IDE) – A digital environment used to develop games, software, hardware, that offers integration from debugging to compiling. Essentially where you write, edit, and run to test your code.
