python 3.x - Boolean operators and Conditions -



python 3.x - Boolean operators and Conditions -

i'm struggling code running perfectly.

question:

write function should_shutdown(battery_level, time_on) returns true if battery level less 4.8 except when time_on less 60. if not case, function returns true if battery level less 4.7. in other situations function returns false.

my code:

def should_shutdown(battery_level,time_on): if battery_level , time_on < 60: homecoming false elif battery_level < 4.8: homecoming true else: homecoming false

it works fine, except when test following:

ans = should_shutdown(4.69, 50) print(ans)

it returns false, right reply should true.

other tests:

should_shutdown(5, 10) expected: false got: false

should_shutdown(4.74, 90) expected: true got: true

should_shutdown(4.74, 50) expected: false got: false

should_shutdown(4.7, 50) expected: false got: false

- should_shutdown(4.69, 50) expected: true got: false

should_shutdown(4.75, 60) expected: true got: true

should_shutdown(4.75, 59) expected: false got: false

def should_shutdown(battery_level, time_on): if battery_level < 4.8: if time_on < 60: homecoming false else: homecoming true else: if battery_level < 4.7: homecoming true else: homecoming false

your problem lies in first if-statement:

if battery_level , time_on < 60:

this same as

if battery_level!=0 , time_on<60:

this because in python, number not 0 evaluates true. perhaps meant:

if battery_level<4.8 , time_on < 60:
