Word scramble
Unscramble the letters and write each key term on the line.
1
FI NN_ESEV(I):
Calls a function that returns True or False and uses that result directly as the if condition. You do not need to write == True. It can also be combined with not, and, or.
2
EDF FTOTA_OS(SLROCE):
A function header with a list parameter. Pass a list when you call it, like total_of([5, 8, 9]), and the function can loop over or read its items.
3
OCPY = ESITM[:]
A function can change a list you pass in, altering the original in place. Make a copy with [:] first if you need to keep the original list unchanged.
4
ESTRLU = []
Start a function with an empty list, append each wanted item inside a loop, then return the finished list after the loop ends. Filtering builds a new list.
5
NTUERR
Sends a value back to the caller. If a function only prints and has no ______, it gives back None, so the caller cannot use the result.
6
EBTTBT.JIEUTORCA
Dot notation reads or changes an attribute stored in an object, like print(pet.name) or pet.age = 5. Each object keeps its own values. A missing attribute causes an AttributeError.
7
EFD SDLOEES(FTIP, MNOUTA):
A method can take extra parameters after self, like amount, and use return to send a value back to the code that called it.
8
2S = MUELAST('NTID')
Creates a second object from the same class. Each object keeps its own attribute values, so changing s2 does not change s1, but both use the same methods.
9
AELE.FSMN = AMNE
Saves a value on the object. Without self. the attribute is lost (AttributeError), and a method missing self as first parameter gives a TypeError for wrong argument count.
