python Instance extension to remove spaces from strings

Example 1:

In[2]: a='   ddd dfe dfd   efre  ddd  '
In[3]: a
Out[3]: '   ddd dfe dfd   efre  ddd  '
In[4]: a.strip()
Out[4]: 'ddd dfe dfd   efre  ddd'
In[5]: a.lstrip()
Out[5]: 'ddd dfe dfd   efre  ddd  '
In[6]: a.rstrip()
Out[6]: '   ddd dfe dfd   efre  ddd'
In[7]: a.replace(' ','')
Out[7]: 'ddddfedfdefreddd'
In[8]: a.split()
Out[8]: ['ddd', 'dfe', 'dfd', 'efre', 'ddd']

Example 2:

In[3]: a = 'dfdfd*dfjdf**fdjfd*22*'
In[4]: a
Out[4]: 'dfdfd*dfjdf**fdjfd*22*'
In[5]: a.split('*')
Out[5]: ['dfdfd', 'dfjdf', '', 'fdjfd', '22', '']
In[6]: a.split('*',2)
Out[6]: ['dfdfd', 'dfjdf', '*fdjfd*22*']
