Strip spaces/tabs/newlines - python

Use str.split([sep[, maxsplit]]) with no sep or sep=None:

From docs:

If sep is not specified or is None, a different splitting algorithm is applied: runs of consecutive whitespace are regarded as a single separator, and the result will contain no empty strings at the start or end if the string has leading or trailing whitespace.

Demo:

>>> myString.split()
['I', 'want', 'to', 'Remove', 'all', 'white', 'spaces,', 'new', 'lines', 'and', 'tabs']

Use str.join on the returned list to get this output:

>>> ' '.join(myString.split())
'I want to Remove all white spaces, new lines and tabs'

If you want to remove multiple whitespace items and replace them with single spaces, the easiest way is with a regexp like this:

>>> import re
>>> myString="I want to Remove all white \t spaces, new lines \n and tabs \t"
>>> re.sub('\s+',' ',myString)
'I want to Remove all white spaces, new lines and tabs '

You can then remove the trailing space with .strip() if you want to.

Use the re library

import re
myString = "I want to Remove all white \t spaces, new lines \n and tabs \t"
myString = re.sub(r"[\n\t\s]*", "", myString)
print myString

Output:

IwanttoRemoveallwhitespaces,newlinesandtabs
