Is there a difference between continue and pass in a for loop in python

Question

Is there any significant difference between the two python keywords continue and pass like in the examples  for element in some list      if not element          pass   and  for element in some list      if not element          continue   I should be aware of

pass could be used in scenarios when you need some empty functions  classes or loops for future implementations  and there s no requirement of executing any code  continue is used in scenarios when no when some condition has met within a loop and you need to skip the current iteration and move to the next one

Difference between pass and continue in a for loop     So why pass in python   If you want to create a empty class  method or block   Examples   class MyException Exception       pass   try     1 0  except     pass   without  pass  in the above examples will throw IndentationError

In your example  there will be no difference  since both statements appear at the end of the loop  pass is simply a placeholder  in that it does nothing  it passes execution to the next statement   continue  on the other hand  has a definite purpose  it tells the loop to continue as if it had just restarted   for element in some list      if not element          pass     print element     is very different from  for element in some list      if not element          continue     print element

Yes  there is a difference  continue forces the loop to start at the next iteration while pass means  there is no code to execute here  and will continue through the remainder or the loop body   Run these and see the difference   for element in some list      if not element          pass     print 1   will print after pass  for element in some list     if not element         continue    print 1   will not print after continue

continue will jump back to the top of the loop  pass will continue processing   if pass is at the end for the loop  the difference is negligible as the flow would just back to the top of the loop anyway

There is a difference between them   continue skips the loop s current iteration and executes the next iteration pass does nothing  It   s an empty statement placeholder      I would rather give you an example  which will clarify this more better    gt  gt  gt  for element in some list          if element    1              print  Pass executed              pass         print element      0 Pass executed 1 2   gt  gt  gt  for element in some list          if element    1              print  Continue executed              continue         print element      0 Continue executed 2

In those examples  no  If the statement is not the very last in the loop then they have very different effects

Yes  there is a difference  Continue actually skips the rest of the current iteration of the loop  returning to the beginning   Pass is a blank statement that does nothing   See the python docs

Yes  they do completely different things   pass simply does nothing  while continue goes on with the next loop iteration   In your example  the difference would become apparent if you added another statement after the if   After executing pass  this further statement would be executed   After continue  it wouldn t    gt  gt  gt  a    0  1  2   gt  gt  gt  for element in a          if not element              pass         print element      0 1 2  gt  gt  gt  for element in a          if not element              continue         print element      1 2

Consider it this way    Pass  Python works purely on indentation  There are no empty curly braces  unlike other languages    So  if you want to do nothing in case a condition is true there is no option other than pass    Continue  This is useful only in case of loops  In case  for a range of values  you don t want to execute the remaining statements of the loop after that condition is true for that particular pass  then you will have to use continue

x    1 2 3 4   for i in x      if i  2           pass   Pass actually does nothing  It continues to execute statements below it           print  This statement is from pass   for i in x      if i  2           continue  Continue gets back to top of the loop And statements below continue are executed           print  This statement is from continue     The output is    gt  gt  gt  This statement is from pass    Again  let run same code with minor changes    x    1 2 3 4  for i in x      if i  2         pass   Pass actually does nothing  It continues to execute statements below it      print  This statement is from pass   for i in x      if i  2          continue  Continue gets back to top of the loop And statements below continue are executed      print  This statement is from continue     The output is -   gt  gt  gt  This statement is from pass  This statement is from pass  This statement is from pass  This statement is from pass  This statement is from continue  This statement is from continue  This statement is from continue    Pass doesn t do anything  Computation is unaffected  But continue gets back to top of the loop to procced with next computation
