python 3.x - Please provide an example of the .format() function where the index field is left blank -


alright bit confused. i'm learning program says index fields .format() method can left blank , if case parameters filled in slots in left right fashion. have tried find answers question haven't found , appreciate if clear me understandable examples , explanations of how use .format() method without index values.

you might this:

print("the value of {} {}".format("foo", 5))

this equivalent to

print("the value of {0} {1}".format("foo", 5))
