什么是缩进中制表符和空格的不一致使用？

Question

I am making a python program that reads an image and creates a level according to every pixel's color. Although , when i run it, I'm getting this error "inconsistent use of tabs and spaces in indentation" at line 139. It's quite frustrating because I can't figure out why it is wrong.

I've already tried changing the indentation size to 2, 4 and 8 but it fixed nothing

Here's my code

#Libraries
import Image
from os import system
from random import randint

#Object class
class object:
    def __init__(self, x , y, facing, image, type):
        self.x = x
        self.y = y
        self.facing = facing
        self.image = image
        self.type = type

#Game variables
entities = []
score = 0
pixels = []

#Read image
pic = Image.open("level1.png", mode="r")

#Get image size
width = pic.size[0]
height = pic.size[1]
picload = pic.load()

#Create pixel array
for y in range(height):
  for x in range(width):
    pixels.append(picload[x, y])

#Read all pixels
x = 0
y = 0

for i in range(len(pixels)):

  #Change x y coordinates
  x += 1
  if x % height == 0: 
    x = 0
    y += 1

  pixel = pixels[i]

  r = pixel[0]
  g = pixel[1]
  b = pixel[2]
  a = pixel[3]

  #Create object based on pixel info
  #If pixel is black
  if r >= 200 and g >= 200 and b >= 200: entities.append(x, y, "r", "■", "wall")
  #If pixel is red
  elif r >= 200 and g <= 50 and b <= 50: entities.append(x, y, "r", "•", "food")
  #if pixel is blue
  elif r <= 50 and g <= 50 and b >= 200: entities.append(x, y, "r", "☺", "player")


#Running the level
while True:

    #output
  print("Output:", output)
  output = ""
  print("Score:", score)

  for y in range(height):
      print("")
      for x in range(width):

          drawed = False
          for i in range(len(entities)):
              entity = entities[i]
              if entity.x == x and entity.y == y and drawed == False:
                  drawed = True
                  print(entity.image, end = "")

          if not drawed: print(".", end="")

    #movement
  for i in range(len(entities)):
      entity = entities[i]
      ii = i
      if entity.type == "player":

        if dir == "w":
            entity.y -= 1
            entity.facing = "u"

        elif dir == "s": 
            entity.y += 1
            entity.facing = "d"

        elif dir == "a": 
            entity.x -= 1
            entity.facing = "l"

        elif dir == "d": 
            entity.x += 1
            entity.facing = "r"

        for h in range(len(entities)):
            centity = entities[h]
            if entity.x == centity.x and entity.y == centity.y and not ii == h:

                if dir == "w":entity.y += 1

                elif dir == "s":entity.y -= 1

                elif dir == "a":entity.x += 1

                elif dir == "d": entity.x -=1

  for h in range(len(entities)):
    entity = entities[h]
    f = entity.facing

    cx = entity.x
    cy = entity.y

    elif f == "l": cx -= 1
    elif f == "u": cy -= 1

You can either use spaces or tabs for indentation. But you cannot mix them. If you use spaces, you need to use the same amount of spaces every time.

Can you try:

#Libraries
import Image
from os import system
from random import randint

#Object class
class object:
    def __init__(self, x , y, facing, image, type):
        self.x = x
        self.y = y
        self.facing = facing
        self.image = image
        self.type = type

#Game variables
entities = []
score = 0
pixels = []

#Read image
pic = Image.open("level1.png", mode="r")

#Get image size
width = pic.size[0]
height = pic.size[1]
picload = pic.load()

#Create pixel array
for y in range(height):
    for x in range(width):
      pixels.append(picload[x, y])

#Read all pixels
x = 0
y = 0

for i in range(len(pixels)):

    #Change x y coordinates
    x += 1
    if x % height == 0: 
        x = 0
        y += 1

    pixel = pixels[i]

    r = pixel[0]
    g = pixel[1]
    b = pixel[2]
    a = pixel[3]

    #Create object based on pixel info
    #If pixel is black
    if r >= 200 and g >= 200 and b >= 200: entities.append(x, y, "r", "■", "wall")
    #If pixel is red
    elif r >= 200 and g <= 50 and b <= 50: entities.append(x, y, "r", "•", "food")
    #if pixel is blue
    elif r <= 50 and g <= 50 and b >= 200: entities.append(x, y, "r", "☺", "player")


#Running the level
while True:

    #output
    print("Output:", output)
    output = ""
    print("Score:", score)

    for y in range(height):
        print("")
        for x in range(width):

            drawed = False
            for i in range(len(entities)):
                entity = entities[i]
                if entity.x == x and entity.y == y and drawed == False:
                    drawed = True
                    print(entity.image, end = "")

            if not drawed: print(".", end = "")

      #input

    dir = input("\n\n####################\nWASD: ").lower()

    #processing

    #movement
    for i in range(len(entities)):
        entity = entities[i]
        ii = i
        if entity.type == "player":

          if dir == "w":
              entity.y -= 1
              entity.facing = "u"

          elif dir == "s": 
              entity.y += 1
              entity.facing = "d"

          elif dir == "a": 
              entity.x -= 1
              entity.facing = "l"

          elif dir == "d": 
              entity.x += 1
              entity.facing = "r"

          for h in range(len(entities)):
              centity = entities[h]
              if entity.x == centity.x and entity.y == centity.y and not ii == h:

                  if dir == "w":entity.y += 1

                  elif dir == "s":entity.y -= 1

                  elif dir == "a":entity.x += 1

                  elif dir == "d": entity.x -=1


    #colisions
    for h in range(len(entities)):
        entity = entities[h]
        f = entity.facing

        cx = entity.x
        cy = entity.y

        if f == "r": cx += 1
        elif f == "l": cx -= 1
        elif f == "u": cy -= 1
        elif f == "d": cy += 1

        for i in range(len(entities)):
            centity = entities[i]
            if centity.x == cx and centity.y == cy: 
                print("a")

Answer 2

You have to keep indentation same through out the code

#Object class
class object:
    def __init__(self, x , y, facing, image, type):
        self.x = x
        self.y = y
        self.facing = facing
        self.image = image
        self.type = type

Here indentation is 4 spaces, but

#Create pixel array
for y in range(height):
  for x in range(width):
    pixels.append(picload[x, y])

here you have 2 space as indentation , this was the error. You should just use tab to keep indentation same everywhere.
