python - string formatting -


I can not find why the colon was released for the second time 

  & gt; & Gt; & Gt; Print '% 5s'% ':': & gt; & Gt; & Gt; Print '% 5s'% ':' '% 2s'% ':' ::

Help me with this

In Python, seismost strings are added: 

  & gt; & Gt; & Gt; T = 'A' 'BCD' & gt; & Gt; & Gt; T 'ABCD'

In its second example, it is equivalent: 

  gt; & Gt; & Gt; According to the preference rules for the% operator of Python, this is:  
  '% 5' '%':% 2s'% ':'  
 
 & Gt; & Gt; & Gt; Print ('% 5s'% ':% 2s')% ':'

or 

  & gt; & Gt; & Gt; Print ':% 2s'% ':' ::
