Error when trying to use _init_ in Python 3.7.0 IDLE

问题

So I was just trying to do same basic Classes stuff in Python.org's Python 3.7.0 IDLE (Shell), and when I tried to run this code:

class Giraffes:
    def _init_(self, spots):
        self.giraffe_spots = spots

gerald = Giraffes(100)

It gave me this error:

Traceback (most recent call last):
File "<pyshell#69>", line 1, in <module>
gerald = Giraffes(100)
TypeError: Giraffes() takes no arguments

Doesn't the init function in class Giraffes make Gerald take parameter self?

I'm just getting started with Python so sorry if this is a newbie mistake or something.

回答1:

The constructor method (like other Python magic methods) is called __init__ (two underscores on each side).
