[英]While Not Loop running more times than intended
我在嘗試制作單詞搜索拼圖生成器時遇到了問題,並且一整天都遇到了多個問題。 (感謝這個社區,我已經解決了大部分問題!)
我現在有另一個問題,我有一個循環,應該找到一個位置來放置一個單詞,放置它,然后移動到下一個單詞。 相反,它是找到單詞可能存在的所有可能位置,並將該單詞放入所有位置。 我只希望每個單詞出現一次。 我認為while not placed
和placed = true
的線條placed = true
會處理這個問題,但它不起作用。
在此先感謝您的幫助,這是我的代碼:
import tkinter as tk
import random
import string
handle = open('dictionary.txt')
words = handle.readlines()
handle.close()
grid_size = 10
words = [ random.choice(words).upper().strip() \
for _ in range(5) ]
print ("The words are:")
print(words)
grid = [ [ '_' for _ in range(grid_size) ] for _ in range(grid_size) ]
orientations = [ 'leftright', 'updown', 'diagonalup', 'diagonaldown' ]
class Label(tk.Label):
def __init__(self, parent, **kwargs):
super().__init__(parent, **kwargs, font=("Courier", 44))
#self.bind('<Button-1>', self.on_click)
#def on_click(self, event):
#w = event.widget
#row, column = w.grid_info().get('row'), w.grid_info().get('column')
#print('coord:{}'.format((row, column)))
#w.destroy()
class App(tk.Tk):
def __init__(self):
super().__init__()
for row in range(grid_size):
for column in range(grid_size):
for word in words:
word_length = len(word)
placed = False
while not placed:
orientation = random.choice(orientations)
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
x_position = random.randrange(grid_size)
y_position = random.randrange(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
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 character_at_new_position != '_':
if character_at_new_position == character:
continue
else:
failed = True
break
if failed:
continue
else:
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
if ( grid[row][column] == grid[new_position_x][new_position_y] ):
grid[row][column] = grid[new_position_x][new_position_y]
Label(self, text=character).grid(row=row, column=column)
placed = True
#if ( grid[row][column] == '_' ):
#txt = random.SystemRandom().choice(string.ascii_uppercase)
#Label(self, text=txt).grid(row=row, column=column)
if __name__ == '__main__':
App().mainloop()
我可以向您保證,您對while
循環的期望是正確的。
In [1]: placed = False
In [2]: i = 0
In [3]: while not placed:
...: i += 1
...: print(i)
...: if i == 5:
...: placed = True
...:
1
2
3
4
5
鑒於此,我懷疑您的代碼總是命中continue
,這意味着它永遠不會命中語句placed = True
,因此是無限循環。 所以,我建議你檢查你的病情continue
如預期。
希望這可以幫助!
