Python issue with finding given string in list of letters

I am fairly new to python and I am trying to figure out how to find if the elements of a list equal a given string?

lists=["a","b",'c']
str1='abc'

I know it is probably easy, but I am having a hard time without using string methods.

Thanks, DD

you can use .join to create a string from your list:

list = ['a', 'b', 'c']
strToComapre = ''.join(list1)

Now you can check if strToComapre is "in" the original str:

if strToCompare in originalStr:
    print "yes!"

If you want a pure compare use:

if strToCompare == originalStr:
    print "yes! it's pure!"

There are lots of options in python i'll add some other useful posts:

Compare string with all values in array

>>> l = ['a', 'b', 'c']
>>> l == list('abc')
True

But, if the order of items in the list can be arbitrary, you can use sets:

>>> l = ['c', 'b', 'a']
>>> set(l) == set('abc')
True

or:

>>> l = ['c', 'b', 'a']
>>> s = set(l)
>>> all(c in s for c in 'abc')
True
