I have tried a couple different methods, but every time I print, there are odd numbers mixed in with the evens! I've only been using python for a couple days, if this turns out to be extremely simple, thanks in advance!

Here is what I ended up with to complete a little excercise asking to sum the even numbers of fibonacci sequence:. Use a list comprehension see: Searching a list of objects in Python. This is good because it leaves list intact, and you can work with evensList as a normal list object. There are always two odd integers between even integers in fibonacci: even, odd, odd, even, odd, odd You can do this with a list comprehension :.

You can also use the filter function. If the list is very long it may be desirable to create something to iterate over the list rather than create a copy of half of it using ifilter from itertools :.

Or by using a generator expression :. You can use list comprehension to generate a new list that contains only the even members from your original list. The advantage of the generator expression is that the whole list is not generated and stored in memory at once, but values are generated as you need them which makes less demand on memory.

There are other important differences you might want to read up on at some point if you are interested. Instead of generating all Fibonacci numbers then filtering for evens, why not generate just the even values? Basically you should create a variable and put your list in and then sort your even numbers list by adding it only the even numbers. CASE 3 checking the values in the range of to get even numbers through function with list comprehension.

CASE 4 This case checks the values in list and prints even numbers through lambda function. Learn more. Asked 8 years ago. Active 9 months ago.

What were the different methods that you tried? Slightly strange you've managed to generate a Fibonacci sequence before you can filter a list Active Oldest Votes. Hope this helps!

I think list comprehension might be a little to advanced for the first days with python Trufa list comprehensions are one of the best parts about python Oh I agree, but this is the best practice - and it leaves him with a list object.

I just think it would be healthier to learn the for loops ins and outs before getting into list comprehension. But again, IMHO. The following sample should solve your problem.

This is if you want to print all the even numbers - if you want to get a list that you can work with, see the answers below. Akavall Akavall Jump to content.

You also have a problem with your types in that you are performing an int function on a list class which I don't believe are compatible. You may want to consider type casting the user input to take int's or floats. Posted 20 March - PM.

I think your code would be clearer if you use different lists and strings for all your needs.

Also, I would prefer to use a count variable here for index and not use range, as it's easier to loop through the initial list, and not its range.

Also, don't use index as it will break if you have repetition of letters in your sentence, as index returns the first occurence of the letter only.

And this is all. The result will contain the elements placed on the following positions 0 -based, so first element is at position 0second at 1 etc.

The [] at the end is just a notation for list slicing. Usually it is in the following form:. If we omitted startthe default 0 would be used. So the first element at position 0because the indexes are 0 -based would be selected. In this case the second element will be selected. Because the second element is omitted, the default is being used the end of the list.

So the list is being iterated from the second element to the end. We also provided third argument step which is 2. Which means that one element will be selected, the next will be skipped, and so on See here: Explain Python's slice notation.

In your code, you explicitly create and increase the counter. In Python this is not necessary, as you can enumerate through some iterable using enumerate :. More on emulating for loops with counter in Python: Accessing the index in Python 'for' loops.

Basically, if you enumerate over a list, you'll get the index x and the value y. Bitwise AND operator is used with 1, and the reason it works because, odd number when written in binary must have its first digit as 1.

Let's check. AND operation with 1 will only return 1 1 in binary will also have last digit 1iff the value is odd. Check the Python Bitwise Operator page for more. S: You can tactically use this method if you want to select odd and even columns in a dataframe.

Let's say x and y coordinates of facial key-points are given as columns x1, y1, x2, etc To normalize the x and y coordinates with width and height values of each image you can simply perform. This is not exactly related to the question but for data scientists and computer vision engineers this method could be useful.
