I have a string, say
a = "Show details1\nShow details2\nShow details3\nShow details4\nShow details5\n"
How do we split the above with the delimiter \n (a newline)?
The result should be
['Show details1', 'Show details2', ..., 'Show details5']
Use a.splitlines(). This will return you a list of the separate lines. To get your "should be" result, add " ".join(a.splitlines()), and to get all in lower case as shown, the whole enchilada looks like " ".join(a.splitlines()).lower().
If you are concerned only with the trailing newline, you can do:
a.rstrip().split('\n')
See, str.lstrip() and str.strip() for variations.
If you are more generally concerned by superfluous newlines producing empty items, you can do:
filter(None, a.split('\n'))
a.split('\n')
would return an empty entry as the last member of the list.so use
a.split('\n')[:-1]
