[問題] 請問怎麼解此題?
Instructions
On line 2, fill in the if statement to check if answer is greater than 5.
On line 4, fill in the elif so that the function outputs -1 if answer is less
than 5.
def greater_less_equal_5(answer):
if ________:
return 1
elif ________:
return -1
else:
return 0
print greater_less_equal_5(4)
print greater_less_equal_5(5)
print greater_less_equal_5(6)
這是codecademy的題目
想問if
return 1是什麼意思?
return -1又是什麼意思?
return 0又是什麼意思?
Tks!
--------------------------------
後來我解出來原來是因為他前面還有段說明
一直把answer當作要寫一個判斷式大於5或小於5
所以方向完全錯誤
