Intro to Python

Indentation

• Indentation is the visual structure of how your code is laid out. It uses tabs to organize code into a hierarchy.

• Indentation refers to the amount of space between lines of code.

• Indentation is a method of commenting code for better readability.

• Indentation is the process of removing unnecessary spaces from code.

Comment

• A message in your code that explains what is going on.

• A type of error in programming.

• A function that returns no value.

• A variable that stores user input.

Print

• Displaying text on the screen

• Creating a graphical image

• Saving a file to disk

• Sending data to a printer

Break Down (Decompose)

• Breaking down your code is splitting it into more functions.

• Breaking down your code is combining multiple functions into one.

• Breaking down your code is removing unnecessary comments.

• Breaking down your code is optimizing the performance of a single function.

Tuple

• A mutable data type that stores an unordered collection of items

• A heterogeneous, immutable data type that stores an ordered sequence of things

• A data type that can only store numbers

• A type of function that returns multiple values

If/Else Statement

• Control structure that lets us run either one section of code or another depending on a test.

• A loop that repeats a section of code multiple times.

• A function that returns a value based on input parameters.

• A method for defining variables in programming.

count()

• A method that counts occurrences of specific items in a list.

• A function that calculates the sum of all items in a list.

• A procedure that sorts items in a list alphabetically.

• A command that removes duplicates from a list.

Exceptions

• Runtime errors in a program. By default, they stop the program.

• Syntax errors that occur during compilation.

• Logical errors that produce incorrect results without crashing.

• Warnings that indicate potential issues but do not stop execution.

left(degrees)

• Command that tells Tracy to turn left and in between parentheses, how many degrees to turn left.

• A command to move right by a specified degree.

• A command that indicates the speed of turning left.

• A command that tells Tracy to stop turning.

Continue

• Rejects all remaining statements in the current iteration of the loop and moves control back to the top of the loop to continue to the next iteration.

• Ends the loop and exits the program immediately.

• Pauses the loop for a specified duration before continuing.

• Skips the current iteration and moves to the next one without executing any further statements.
