Compsci: lecture 9/4

Page 1

calling a function: gives the information you wanted to pass

python doesn't care as long as you start and end with the same quotes. double or single quotes

unnecessary to memorize function codes

strings are fixed, lists can be changed

(same diff as constant and a variable)

compsci start counting with "0"

colon (:) indicates slicing of a list

number before indicates where slicing starts, and number after where slicing ends

b-a is number of things it will slice up [a:b]

[:x] means it starts at 0 and ends right before x

[a:b:c] has a stride/step of c. unspecified c is 1
