[英]TypeError: must be string without null bytes, not str
I'm trying to run this code, to run the same command (with little changes) with every frame that I have: 我正在尝试运行此代码,以便在我拥有的每个帧中运行相同的命令(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("../")
I run this and I get this error: 我运行这个,我得到这个错误:

TypeError: must be string without null bytes, not str
I searched in internet, but I can't find a good answer. 我在互联网上搜索,但找不到很好的答案。
The problem is with the \\ char that should either be double escaped, ie changed to "\\\\" Or alternatively add an "r" before the string decleration: 问题在于\\ char应该被两次转义,即更改为“ \\\\”,或者在字符串解串之前添加“ r”:
pml_cmd = r"pymol urei%s.pdb ..." pml_cmd = r“ pymol urei%s.pdb ...”
You get this particular error since somewhere along the string there is a \\0 which is interpreted as a NULL char 您会收到此特定错误,因为在字符串的某处有一个\\ 0,它被解释为NULL字符
I was able to resolve this error by commenting out the print
: 我可以通过注释掉
print
来解决此错误:
for tarfileobj in inputs:
# print(tarfileobj)
tarfileobj.extractall(path=t, members=None)
I could have done print(tarfileobj.split)
or printed the repr
or removed \\0
null bytes, or if its a tarfile, just extract it. 我可以完成
print(tarfileobj.split)
或打印repr
或删除\\0
空字节,或者如果它是tarfile,只需将其解压缩即可。
