TypeError：必须是字典，而不是str

Question

嘿家伙我试图在Python中使用参数变量，但无法在终端执行程序。

计划：

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()不带命令的参数。请尝试使用subprocess。
