我正在努力学习python，我正在做第一个argv练习，并获得一个

Question

在艰苦学习python练习13中，我们第一次导入了argv。代码如下：

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

我得到的结果是：

donny@donny:~/Documents/pygame-scripts$ python ex13.py first second third
Traceback (most recent call last):
  File "ex13.py", line 1, in <module>
    d
NameError: name 'd' is not defined

我想不通。我在谷歌上搜索了一下，确认我完全复制了代码。任何帮助都将不胜感激。你知道吗

Answer 1

问题是print的参数之间缺少逗号。你知道吗

请尝试以下操作：

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

编辑：

要使代码与python3兼容，请使用print(arg1, arg2)而不是print arg1, arg2。你知道吗

Answer 2

字符串后需要,。如下所示

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