我试图用in-line,lambda函数来执行一些if/else条件,我得到"unsupported operand type(s) for +: 'int' and 'function'"
错误。在这里,我试图将set_duration设置为1.5,除非它的第一次和最后一次数组迭代。你可以看看并提供任何提示。期待。python lambda if/else条件失败:'int'和'function'冲突
for idx, string in enumerate(lines):
duration = 10
clips = []
clips.append(ImageClip(os.path.join(folder,"gradient.png"))
.set_duration(lambda idx: 3 if (idx == 0 and lines[len(lines) - 1]) else 1.5)
)
clips.append(ImageClip(os.path.join(folder,"image-{0}.png"))
.resize(width=800)
.set_duration(lambda idx: 3 if (idx == 0 and lines[len(lines) - 1]) else 1.5)
.margin(right=60, opacity=0)
.set_pos(("right","center"))
)
clips.append(ImageClip(os.path.join(folder, "big-append.png"))
.resize(width=900)
.margin(left=60,opacity=0)
.set_duration(lambda idx: 3 if (idx == 0 and lines[len(lines) - 1]) else 1.5)
.set_pos(("left", "center"))
)
// rest of the code...

编辑:对不起,只是一个盲目的猜测,试试看它适用于我...你确定错误指向到这部分代码中?你在这里没有“+”......错误基本上说你试图将INT和FUNCTION一起添加:)由于“不支持的操作数类型为+:'int'和'function ''并不是指你的lambda中的“和”。 –
@PeterMajko,嗨不是迄今为止 –
@PeterMajko,它的影片模块,所以ImageClip是否有标准类 –
