It is better to use `re.finditer` when iterate over text and save to file. Look like this. import re data = '''\ line2 jdsbvbsf line3 <match name="item1" rhs="domain.com"></match> line4 <match name="item2" rhs="domainn.com"></match> line5 <match name="item2" rhs="1010data.com"></match>''' with open('result.txt', 'w') as f_out: for match in re.finditer(r'rhs="(.*)"', data): f_out.write('{}\n'.format(match.group(1))) '''Output--> domain.com domainn.com …

The import statement will return the top level module of a package. You can try this. varhelp = __import__("sys").path But be careful and try to keep "magic stuff" away from import statement. [import(doc)](http://docs.python.org/2/library/functions.html#__import__) > Note This is an advanced function that is not needed in everyday Python programming, unlike importlib.import_module().

The list show only integer,so why convert at all. >>> lst = [120, [10, 20, 30]] >>> lst[0] 120 >>> lst[1] [10, 20, 30] >>> type(lst[0]) <type 'int'> >>> balance, withdrawal = lst[0], lst[1] >>> balance 120 >>> withdrawal [10, 20, 30]
