Python转义sys argv中的特殊字符

标签: python string bash command-line argv

我有一个带有sys.argv的脚本,输入可能包含特殊字符(分号)。我只需要输入字符串,但分号会把一切都搞砸......

我有:

def myscript(text)
    print text


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

我试试:

>>  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""

我明白了:

'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

我只想将整个字符串放入脚本中,无论其内部是什么..

我试过了:

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

这不是python的问题,你需要在调用shell中转义它。只需将引号转义为\",将分号转义为\;

$ 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"

这不是python问题,而是 bash 问题。 Bash认为;(分号)正在分离一个新的bash命令。你需要逃脱它。
