Googled the strip () function, but it only removes the first and last space, and I need everything.
For example, if a = 'sd dfsdf dfsfs' , then you need to get a = 'sddfsdfdfsfs' .
Is there such a function or is it necessary to do something through the loop?

a.replace ('', '')

strip () can remove not only whitespace, but tabs and other characters that are considered whitespace, including Unicode whitespace, if strip () is called on a Unicode string:

& gt; & gt; & gt; import string
& gt; & gt; & gt; string.whitespace
'\ t \ n \ x0b \ x0c \ r'
& gt; & gt; & gt; string.whitespace.strip ()
''
& gt; & gt; & gt; import sys
& gt; & gt; & gt; s = '' .join (unichr (i) for i in xrange (sys.maxunicode) if unichr (i) .isspace ())
& gt; & gt; & gt; s [: 15]
u '\ t \ n \ x0b \ x0c \ r \ x1c \ x1d \ x1e \ x1f \ x85 \ xa0 \ u1680 \ u180e \ u2000'
& gt; & gt; & gt; s.strip ()
u ''

Therefore, an analogue of strip () that removes whitespace in the entire line: s = '' .join (s.split ()) .

Or, the same thing, using regular expressions: s = re.sub (r '\ s +', '', s, flags = re.UNICODE) .

Or, in code where performance is important, bytes.translate () can be used to remove all standard (string.whitespace in C locale) whitespace from ascii lines:

& gt; & gt; & gt; b'a \ tb \ nc'.translate (None, b '\ t \ n \ v \ f \ r')
'abc'

If you have something like this

"def m e gaDifficu ltFun ction (x):")

and want to give

def m e gaDifficu ltFun ction (x):

then you can solve by using join () and split () methods:

return "" .join (code.split ())

If you don’t know the number of spaces and tabs, the easiest way is:

a = 'Some string with meny space or tabs'
b = a.split ()
b = '' .join (b)
b & gt; & gt; & gt; Somestringwithmenyspaceortabs
