蟒蛇逃脱在sys argv的特殊字符 [英] Python escape special characters in sys argv

问题描述

我有一个脚本，需要sys.argv中和输入可能包含特殊字符（分号）。我只需要输入的字符串，但分号打乱了一切。

我有：

 高清的MyScript（文本）
    打印文本
一个=的MyScript（sys.argv中[1]）
打印一
 

我尝试：

 ＆GT;＆GT;蟒蛇script.py一边说着，她招呼王子瓦西里库拉金，高级别和重要性的人，谁是第一个在她接待安娜夫娜的到来。已经有一些日子咳嗽。她，正如她所说，痛苦从洛杉矶流行性感冒;流行性感冒是然后在圣彼得堡一个新词
 

我得到：

 说完这些话，她招呼王子瓦西里库拉金，高级别和重要性的人，谁是第一个在她抵达接待。安娜·帕夫洛夫娜已经有一段日子咳嗽。她，因为她说，'痛苦
没有
庆典：流行性感冒：命令未找到
 

我只是想获得整个字符串到脚本不管里面是什么吧..

我试过：

  A =的MyScript（再版（sys.argv中[1]））
一个=的MyScript（STR（sys.argv中[1]））
 

解决方案

这不是蟒蛇的事情，你需要躲避它调用shell。简单地逃避报价为 \\和分号为 \\;

  $蟒蛇testme.py一边说着，她招呼王子瓦西里库拉金，高级别和重要性的人，谁是第一个在她抵达接待安娜夫娜曾经有过咳嗽了几天她，因为她说，从洛杉矶流行性感冒患\\。流行性感冒是然后在圣彼得堡\\一个新词说完这些话，她招呼王子瓦西里库拉金，高级别和重要性的人，谁是第一个在她抵达接待。安娜·帕夫洛夫娜已经有一段日子咳嗽。她，因为她说，患距离la流行性感冒，流行性感冒是然后在圣彼得堡一个新词
 

I have a script that takes sys.argv and the input may contain special characters (semicolon). I just need the input as string, but semicolon messes everything up..

I have:

def myscript(text)
    print text


a = myscript(sys.argv[1])
print a

I try:

>>  python script.py "With these words she greeted Prince Vasili Kuragin, a man of high rank and importance, who was the first to arrive at her reception. Anna Pavlovna had had a cough for some days. She was, as she said, suffering" from la grippe; grippe being then a new word in St. Petersburg""

I get:

'With these words she greeted Prince Vasili Kuragin, a man of high rank and importance, who was the first to arrive at her reception. Anna Pavlovna had had a cough for some days. She was, as she said, suffering'
None
bash: grippe: command not found

I just want to get the whole string into the script no matter what is inside it..

I tried:

a = myscript(repr(sys.argv[1]))
a = myscript(str(sys.argv[1]))

解决方案

it's not a matter of python, you need to escape it in the calling shell. simply escape quotes as \" and semicolons as \;.

$ python testme.py "With these words she greeted Prince Vasili Kuragin, a man of high rank and importance, who was the first to arrive at her reception. Anna Pavlovna had had a cough for some days. She was, as she said, suffering\" from la grippe; grippe being then a new word in St. Petersburg\""

With these words she greeted Prince Vasili Kuragin, a man of high rank and importance, who was the first to arrive at her reception. Anna Pavlovna had had a cough for some days. She was, as she said, suffering" from la grippe; grippe being then a new word in St. Petersburg"
