from sys import argv #从python功能库中导入功能 “features"真正的名称是:modules / libraries
script, first, second, third = argv # argv是“参数变量”,解变量
print "The script is called:", script #屏幕上显示脚本的名字
print "Your first variable is:", first #屏幕上显示第一个变量的名字
print "Your second variable is:", second #屏幕上显示第二个变量的名字
print "Your third variable is:", third #屏幕上显示第三个变量的名字
print "Your first variable is:", first #屏幕上显示第一个变量的名字
print "Your second variable is:", second #屏幕上显示第二个变量的名字
print "Your third variable is:", third #屏幕上显示第三个变量的名字
$ python ex13.py first 2nd 3rd
#命令行键入
The script is called: ex13.py
Your first variable is: first
Your second variable is: 2nd
Your third variable is: 3rd
The script is called: ex13.py
Your first variable is: first
Your second variable is: 2nd
Your third variable is: 3rd
question 不会解!!!!
结合raw_input和argv写一个脚本。
from sys import argv
script, first = argv
print "How %s are your?" % first
write = raw_input()
print "Your %s is %s." % (first, write)
输出:
root@he-desktop:~/mystuff# python ex13.py old
How old are your?
25
Your old is 25.
root@he-desktop:~/mystuff# python ex13.py old
How old are your?
25
Your old is 25.
总结:
script(脚本)是在命令行里给变量
raw_input是屏幕提示键盘键入变量
finally
from sys import argv
script, first = argv
print "How %s are you?" %first
age=raw_input("How %s are you?")
print "I'm %s years %s." %(age, first)
本文通过实例展示了如何使用 Python 的 argv 和 raw_input 功能来接收并处理命令行参数及用户输入,帮助读者理解这两种获取外部数据方式的区别。
