为什么我的程序返回 NameError: name 'self' is not defined as the error

Question

I'm trying to get a program to tell me how many posts I've liked using the InstagramAPI module. It's returning NameError: name 'self' is not defined and I'm not sure why.

This is my code:

from InstagramAPI import InstagramAPI
import time, json, re
import json
import requests
import os
username = ''
password = ''

i = InstagramAPI(username, password)

i.login()

def getTotalLikedMedia(self, scan_rate=1):
        next_id = ''
        liked_items = []
        for x in range(0, scan_rate):
            temp = self.getLikedMedia(next_id)
            temp = self.LastJson
            try:
                next_id = temp["next_max_id"]
                for item in temp["items"]:
                    liked_items.append(item)
            except KeyError as e:
                break
        return liked_items

getTotalLikedMedia

Answer 1

self represents the instance of the class . By using the argument bound to the name self we can access the attributes and methods of the class .

You appear to be defining a method without the class it is supposed to be a method of.

class something:
   def __init__(self, something):
      self.something = something

ins = something()

Answer 2

Without posting entire traceback it is impossible to know what really happened. I guess that the code you posted is not how it really looks like on your computer. It seems like a method definition but here it is just a plain function, where self is just an argument called... well, self. Technically nothing is wrong with that, and calling that method would probably result in raising AttributeError , when the interpreter tries to execute line temp = self.getLikedMedia(next_id) , unless you passed as self some object that does have the method getLikedMedia() .
