Python and Line Breaks

Question

With Python I know that the \"\\n\" breaks to the next line in a string, but what I am trying to do is replace every \",\" in a string with a \'\\n\'. Is that possible? I am kin

Answer 1

>>> str = 'Hello, world'  
>>> str = str.replace(',','\n')

Hello  
 world

>>> str_list=str.split('\n')
>>> print str_list
['Hello', ' world']

Answer 2

Try this:

text = 'a, b, c'
text = text.replace(',', '\n')
print text

For lists:

text = ['a', 'b', 'c']
text = '\n'.join(text)
print text

Answer 3

You can insert a literal \n into your string by escaping the backslash, e.g.

>>> print '\n'; # prints an empty line

>>> print '\\n'; # prints \n
\n

The same principle is used in regular expressions. Use this expresion to replace all , in a string with \n:

>>> re.sub(",", "\\n", "flurb, durb, hurr")
'flurb\n durb\n hurr'
