python 3 print statement clarification -

In Python 2, Python did not have a print statement function, while in Python 3 it was converted to function

when I type print ( to me some hovertext (or something like this) from

  print (value, ..  < / Pre> 
 I know what the value is, but what is the explanation of what these other variables mean and the benefits of the print statement of Python 2 above Python 2 are  (especially Sep = '') < / Code>   
 
 
 When you provide many arguments in  print  Usually divided by a place:  
  & gt; & gt; print (1, 2, 3) 1 2 3   
  sep  lets you do something else:  
  & gt; & gt; & gt; Normally,  print  add a new line at the end Print (1, 2, 3, sep = ',') 1, 2, 3   
  End  lets you change this:  
  & gt; & Gt; & Gt; Print ('Hello.', End = '') Hello. & Gt; & Gt; & Gt;   
 Typically will write the  print  standard.  file  lets you change this:  
  & gt; & Gt; & Gt; ("Hello, world!", File = f) ...   
 Normally open with ('test.txt', 'w') as . .. print does not flush the stream explicitly if you want to avoid an additional  sys.stdout.flush () , then you can use  flush  Its effect is generally hard to see, but it should show it without  flush = true :  
  & gt; & Gt; & Gt; Import time & gt; & Gt; & Gt; While true: ... print ('.', End = '', flush = true) ... time.sleep (0.5)
