python 的词搜索生成器问题

Question

我正在尝试实现一些代码，这些代码运行是一个搜索游戏生成器，在数组中包含一些单词，所以我决定使用一些在视频中测试过的代码，在视频中似乎是运行正常，但是当我运行代码冻结时，所以我想知道发生了什么：

这是我正在谈论的代码：

import random
import string

words = ['PYTHON', 'ROBBIE', 'GITHUB', 'BEEF']
grid_size=15
grid = [['_' for _ in range(grid_size)] for _ in range(grid_size)]
orientations = ['leftright','updown','diagonalup','diagonaldown']
#Prints the grid
def print_grid():
    for x in range(grid_size):
        print('\t'*5+' '.join(grid[x]))
#Generates grid
def generategrid(words):
    for word in words:
        word_length = len(word)
        placed = False
        while not placed:
            orientation = random.choice(orientations)
            #Sets orientation given by a random number
            if orientation == 'leftright':
                step_x=1
                step_y=0
            if orientation == 'updown':
                step_x = 0
                step_y = 1
            if orientation == 'diagonalup':
                step_x = 1
                step_y = 1
            if orientation == 'diagonaldown':
                step_x = 1
                step_y = -1
        #We generate a random starting point, then we calculate the ending point and if it exceeds the limit, we calculate the number again
        x_position = random.randint(0,grid_size)
        y_position = random.randint(0,grid_size)
        ending_x = x_position + word_length*step_x
        ending_y = y_position + word_length*step_y
        if ending_x < 0 or ending_x >= grid_size: continue
        if ending_y < 0 or ending_y >= grid_size: continue
        failed=False
        #we set the word on the previously given position
        for i in range(word_length):
            character = word[i]
            new_position_x = x_position + i*step_x
            new_position_y = y_position + i*step_y
            character_at_new_position = grid[new_position_x][new_position_y]
            #if there is some character that could be used to form the word
            if character_at_new_position != '_':
                if character_at_new_position == character:
                        continue
                else:
                        failed = True
                        break      
        if failed:#We do the process from above again until we can put the word on the grid 
            continue
        else:
            #Everything worked perfectly and the word was placed without problems
            for i in range(word_length):
                character = word[i]
                new_position_x = x_position + i*step_x
                new_position_y = y_position + i*step_y
            grid[new_position_x][new_position_y] = character
            placed = True
generategrid(words)
print_grid()

当我运行程序冻结时，但是在视频中这段代码似乎运行良好。任何建议或观察将不胜感激！

Answer 1

您在 while not placed: 之后有一个无限循环。我不完全确定代码的意图是什么，但我认为你的意思是在一定时间后设置 placed = True。

在代码的更下方，它正是这样做的，所以我猜是缩进错误。在 Python 中，缩进定义了循环的范围，因此请仔细检查您正在查看的示例中的缩进。
