我目前正在pygame中为一款游戏制作地图编辑器，使用tile地图。 关卡是由以下结构中的块构建而成的(尽管要大得多):
level1 = (
(1,1,1,1,1,1)
(1,0,0,0,0,1)
(1,0,0,0,0,1)
(1,0,0,0,0,1)
(1,0,0,0,0,1)
(1,1,1,1,1,1))
其中“1”是一堵墙，“0”是一个空的空气。
下面的代码基本上是处理块类型变化的代码:
clicked = pygame.mouse.get_pressed()
if clicked[0] == 1:
currLevel[((mousey+cameraY)/60)][((mousex+cameraX)/60)] = 1
但由于关卡存储在元组中，我无法更改不同块的值。我如何以简单的方式改变关卡中的不同值?
当前回答
列表到元组和返回可以这样做
import ast, sys
input_str = sys.stdin.read()
input_tuple = ast.literal_eval(input_str)
l = list(input_tuple)
l.append('Python')
#print(l)
tuple_2 = tuple(l)
# Make sure to name the final tuple 'tuple_2'
print(tuple_2)
其他回答
在我的例子中，我想合并行/列表:
a = ['Tom', 'Dick', 'Harry']
b = ['20', '32', '14']
c = ['foo', 'bar', 'blah']
lines = [list(row) for row in zip(a, b, c)]
lines = [['Tom', '20', 'foo'], ...]
将元组转换为列表:
>>> t = ('my', 'name', 'is', 'mr', 'tuple')
>>> t
('my', 'name', 'is', 'mr', 'tuple')
>>> list(t)
['my', 'name', 'is', 'mr', 'tuple']
将列表转换为元组:
>>> l = ['my', 'name', 'is', 'mr', 'list']
>>> l
['my', 'name', 'is', 'mr', 'list']
>>> tuple(l)
('my', 'name', 'is', 'mr', 'list')
列表到元组和返回可以这样做
import ast, sys
input_str = sys.stdin.read()
input_tuple = ast.literal_eval(input_str)
l = list(input_tuple)
l.append('Python')
#print(l)
tuple_2 = tuple(l)
# Make sure to name the final tuple 'tuple_2'
print(tuple_2)
从Python 3.5 (PEP 448—Additional Unpacking Generalizations)开始，可以使用以下文字语法将元组转换为列表:
>>> t = (1,2,3)
>>> lst = [*t]
>>> lst
[1, 2, 3]
>>> *lst, # back to tuple
(1, 2, 3)
列表推导式可用于将元组的元组转换为列表的列表:
>>> level1 = (
... (1,1,1,1,1,1),
... (1,0,0,0,0,1),
... (1,0,0,0,0,1),
... (1,0,0,0,0,1),
... (1,0,0,0,0,1),
... (1,1,1,1,1,1))
>>> level1_list = [[*row] for row in level1]
>>> level1_list
[[1, 1, 1, 1, 1, 1],
[1, 0, 0, 0, 0, 1],
[1, 0, 0, 0, 0, 1],
[1, 0, 0, 0, 0, 1],
[1, 0, 0, 0, 0, 1],
[1, 1, 1, 1, 1, 1]]
>>> *((*row,) for row in level1_list),
((1, 1, 1, 1, 1, 1),
(1, 0, 0, 0, 0, 1),
(1, 0, 0, 0, 0, 1),
(1, 0, 0, 0, 0, 1),
(1, 0, 0, 0, 0, 1),
(1, 1, 1, 1, 1, 1))
>>> _ == level1
True
为什么不试着将它的类型从元组转换为列表，反之亦然。
level1 = (
(1,1,1,1,1,1)
(1,0,0,0,0,1)
(1,0,0,0,0,1)
(1,0,0,0,0,1)
(1,0,0,0,0,1)
(1,1,1,1,1,1))
print(level1)
level1 = list(level1)
print(level1)
level1 = tuple(level1)
print(level1)
