Word scramble
Unscramble the letters and write each key term on the line.
1
RECSO <- 0 SBCMEOE ERSOC = 0
Pseudocode steps map to Python lines: <- becomes =, input becomes input(), if becomes if with a colon, for becomes for in range(). END IF becomes un-indenting.
2
OAGLBL
A keyword used inside a function so it can assign to a variable defined outside all functions, instead of creating a new local variable with the same name.
3
FDE INMA(): EERTG()
A function can call another function inside its body. Big problems get split into small helper functions that each do one job, like boxes in a decomposition.
4
FED AMNI():
Defines a function called main that holds the main steps of your program. You call main() once at the end of the file, after the other functions are defined, to start the program.
5
ESO-INAEOMNINDL RAYAR
A named, ordered collection of elements of the same data type. Each element is reached by its index, its position number (0-based in Python, often 1-based in pseudocode).
6
OCRSES = [0] * 01
Creates a one-dimensional array (list) of 10 elements that all start with the value 0. Change the number to set the size, or use '' for strings.
7
ROF TMIE NI SI_TYLM:
Runs the indented block once for each value in the list. The variable item holds the current value each time round, starting with the first and finishing with the last.
8
ORF I NI GELAA(NRE(RNR)):
Loops i through every index of arr, so arr[i] can be read or changed and you know each element's position. Used for totals, finding the largest value and editing in place.
9
WOOG[RCD][IRL]
A 2D array stores data in rows and columns like a table. Use the row index first, then the column index, to reach one element, such as a seat in a seating plan.

1RECSO <- 0 SBCMEOE ERSOC = 0 → score <- 0 becomes score = 0 — Pseudocode steps map to Python lines: <- becomes =, input becomes input(), if becomes if with a colon, for becomes for in range(). END IF becomes un-indenting.
