from sys import argv
input(argv)

script,first,second,third = argv

print("The script is called:",script)
print("Your first varilable is:",first)
print("Your sencond variable is:",second)
print("Your third variable is:",third)


这段代码在pycharm 运行出错，提示代码：
Traceback (most recent call last):
  File "C:/Users/Administrator/PycharmProjects/ex1.py/ex13.py", line 4, in <module>
    script,first,second,third = argv
ValueError: not enough values to unpack (expected 4, got 1)

在命令行中输入 python ex13.py  1 2 4 出现无效语法错误 怎么解决 命令行编辑python程序

大兄弟，你input 的参数 argv就一个值
从你这行代码 script,first,second,third = argv  来看
你是期望 argv为4个值的
但是从你报错来看，not enough values to unpack (expected 4, got 1)

提示拆开你输入的数据包后，没有足够的值来匹配，期望4，你就输入了1
