Django provides it  You can use either       forloop counter    index starts at 1     forloop counter0    index starts at 0    In template  you can do      for item in item list           forloop counter      starting index 1        forloop counter0      starting index 0        do your stuff    endfor      More info at  for   Built-in template tags and filters   Django documentation

for days in days list         lt h2 gt   Day    forloop counter    - From    days from location    to    days to location    lt  h2 gt     endfor     or if you want to start from 0    for days in days list             lt h2 gt   Day    forloop counter0    - From    days from location    to    days to location    lt  h2 gt         endfor

Django HTML template doesn t support index as of now   but you can achieve the goal   If you use Dictionary inside Dictionary in views py then iteration is possible using key as index  example      for key  value in DictionartResult items     lt  -- dictionartResult is a dictionary having key value pair-- gt   lt tr align  center  gt       lt td  bgcolor  Blue  gt  lt a href   value ProjectName   gt  lt b gt   value ProjectName   lt  b gt  lt  a gt  lt  td gt       lt td gt     value atIndex0     lt  td gt           lt  -- atIndex0 is a key which will have its value   you can treat this key as index to resolve-- gt       lt td gt     value atIndex4     lt  td gt       lt td gt     value atIndex2     lt  td gt   lt  tr gt     endfor      Elseif you use List inside dictionary then not only first and last iteration can be controlled  but all index can be controlled  example      for key  value in DictionaryResult items         lt tr align  center  gt         for project data in value               if  forloop counter  lt   13      lt  -- Here you can control the iteration-- gt                 if forloop first                     lt td bgcolor  Blue  gt  lt a href   project data   gt  lt b gt     project data     lt  b gt  lt  a gt  lt  td gt   lt  -- it will always refer to project data 0 -- gt                 else                     lt td gt     project data     lt  td gt   lt  -- it will refer to all items in project data   except at index  0 -- gt                 endif                   endif           endfor         lt  tr gt     endfor      End If        Hope have covered the solution with Dictionary  List  HTML template  For Loop  Inner loop  If Else  Django HTML Documentaion for more methods  https   docs djangoproject com en 2 2 ref templates builtins

I think you could call the id  like this    for days in days list         lt h2 gt   Day    days id    - From    days from location    to    days to location    lt  h2 gt     endfor

Also one can use this      if forloop first      or     if forloop last
