different baviour in script vs shell session

[xiaoyisimonguo]

Hi folks

I am new to python world

I recently wrote a little script to process system Verilog file, repair syntax violations, by regular expression matching

fixFileInFileList.py -i inp0 inp1 inp2

the matching strings were inputted in inp1:
('\S+\.h', '\S+\.H')
By the way, I tried square parenthesis also

That should interpreted as two elements list:

>>> excpType1 = ('\S+\.h' '\S+\.H')
>>> print(str(len(excpType1)))
12
>>> excpType1 = ('\S+\.h', '\S+\.H')
>>> print(str(len(excpType1)))
2

But in the program I placed print statement revealed totally unexpected results:

                  print(excpType1+str(len(excpType1)))
                  print(excpType1)
                  print(excpType1[einx])

yielded:

Output:
('\S+\.h', '\S+\.H')20
('\S+\.h', '\S+\.H')
(
In case of square parenthesis:
['\S+\.h', '\S+\.H']20
['\S+\.h', '\S+\.H']
[

I am struggling for a few days now, please help,
What did I do wrong?
Why script functioned differently versus interpreter run, I even uses the same imports with script?
Or a different implementation to do the same thing?
