regular expression to remove space python

r = re.compile(r"^s+", re.MULTILINE)
r.sub("", "a
 b
 c") # "a

c"

# or without compiling (only possible for Python 2.7+ because the flags option
# didn't exist in earlier versions of re.sub)

re.sub(r"^s+", "", "a
 b
 c", flags = re.MULTILINE)

# but mind that s includes newlines:
r.sub("", "a
