$ex13.py 源码
#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)
from sys import argv #导入sys模组的argv功能
script, first, second, third, fouth, fifth = argv #解包并赋值
print (script)
print (first)
print (second)
print (third)
print (fouth)
print (fifth)
执行命令：
python .\ex13.py 1st 2nd 3rd 4th 5th
输出结果：
使用参数时需要导入sys模组的argv功能
然后对argv进行解包，分别赋值给左侧的变量
$ex14.py 源码
from sys import argv
prompt = "\\:"
script, lll = argv
print ("Are you OK?")
status = input(prompt)
print ("So %r, your status is %r !" % (lll,status))
调用命令：
python .\ex14.py 22
输出结果：
Are you OK?
\:n
So '22', your status is 'n' !
