TypeError：必須是字典，而不是str

Question

嘿傢伙我試圖在Python中使用參數變量，但無法在終端執行程序。

計劃：

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 

輸出：

>>> 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()不帶命令的參數。請嘗試使用subprocess。
