我正在尝试运行此代码,对我拥有的每一帧运行相同的命令(几乎没有变化):

traj.reset()
import os
#os.chdir(outname)
for i, frame in enumerate(traj):
    frame.superpose()
    comando = "python hollow.py -c constraint -o hollow_%s.pdb urei%s.pdb" % (i, i)
    os.system(comando)
    pml_cmd = "pymol urei%s.pdb hollow_%s.pdb -c -d 'as cartoon, urei%s;color gray90, urei%s;center chain A;set_view (\-0.605158150,0.089404292,0.791067421,\0.795849979,0.093013920,0.598304033,\-0.020089993,0.991641700,-0.127439827,\0.000000000,0.000000000,-202.017959595,\-28.771762848,-7.683309555,10.745590210,\-568.485290527,972.520690918,-20.000000000);bg white;as sphere, hollow_%s;color cyan, hollow_%s;ray;save urei%s.png' " % (i, i, i, i, i, i, i)
    os.system(pml_cmd)
    #remove = "rm urei%s.pdb hollow_%s.pdb" % (i, i)
    #os.system(remove)
os.chdir("../")

我运行这个,我得到这个错误:

TypeError                                 Traceback (most recent call last)
<ipython-input-8-53cd3e7bd107> in <module>()
      7     os.system(comando)
          8     pml_cmd = …

我正在尝试在10x10的网格中写入包含多个图像（100）的文件。我使用3进行迭代以：

-打开文件-设置坐标（i，j）

问题是当我查看文件时，只能看到最后一张图像多次。也许每次程序进入for循环时文件都会被覆盖。到目前为止，我找不到解决方案。

代码是：

    import Image

    from os import listdir
    from os.path import isfile, join
    files = [ f for f in listdir("/mnt/hgfs/Documents/Notebooks/test1/") if isfile(join("/mnt/hgfs/Documents/Notebooks/test1/", f)) ]

    new_im = Image.new('RGB', (3000,3000))

    for i in xrange(0,3000,300):
        for j in xrange(0,3000,300):
            for ima in files:
                #paste the image at location i,j:
                im = Image.open(ima)
                im.thumbnail((300,300))
                new_im.paste(im, (i,j))

    new_im.save("hola.png")

谢谢！
