我不明白如何使用类。当我尝试使用该类时,以下代码给了我一个错误。
class MyStuff:
def average(a, b, c): # Get the average of three numbers
result = a + b + c
result = result / 3
return result
# Now use the function `average` from the `MyStuff` class
print(MyStuff.average(9, 18, 27))
错误:
File "class.py", line 7, in <module>
print(MyStuff.average(9, 18, 27))
TypeError: unbound method average() must be called with MyStuff instance as first argument (got int instance instead)
怎么了?
