python - Simple for loop explanation -

-

why code...

alist = ['cat','dog','cow'] item in alist:         print alist

output

['cat', 'dog', 'cow'] ['cat', 'dog', 'cow'] ['cat', 'dog', 'cow']

while changing print alist item outputs:

cat dog cow

i understand when printing alist print list many times there elements in list guess don't understand why different.

i grateful if explain difference me or point me in right direction.

  • you have list - contains cat, dog, , cow.
  • then say: each thing in list, print list.
  • you have 3 things in list (cat, dog, , cow) list gets printed 3 times.

  • when switch statement print item instead of print alist saying each thing in list print thing - each thing in list gets printed,

    ie cat, dog, cow.
