Python escape special characters in sys argv

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]))

This is not a python issue, it's a bash issue. Bash thinks the ; (semicolon) is separating a new bash command. You need to escape it.

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\""
