python - TypeError：必须是 dict，而不是 str

Question

嘿伙计们，我试图在 Python 中使用参数变量，但是无法在终端上执行程序。

程序：

from sys import argv

script,first,second,third = argv

print "The script is called:", script
print "Your first variable is:", first
print "Your second variable is:", second 
print "Your third variable is:", third

输出：

>>> execfile("lesson13.py","dog","cat")
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: must be dict, not str
>>> 

Answer 1

execfile()不接受命令参数。尝试subprocess改用。
