If String is Number & Interview with Guido
Hello, checkiomates🐱👤! That is NOT my photo!) ⤴
Have not write you for a while...but education and fun never stops, yeah?! 📚 So, this week CheckiO team prerares for you a few missions and fresh topics to read! Let's get party started!
🏁 NEW MISSIONS:
is_number("34") == True is_number("df") == False is_number("") == False
is_number("+10.0") == True is_number("1OOO") == False is_number("1.") == True
Feed Pigeons by bryukh - Pay your attention to this interesting mission! It's not new, but has everything we like - not very easy, has a lot of solutions to learn something new, highly rated hints and animated tests! I start to feed one of the pigeons. A minute later two more fly by and a minute after that another 3. Then 4, and so on. One portion of food lasts a pigeon for a minute, but in case there's not enough food for all the birds, the pigeons who arrived first ate first. Pigeons are hungry animals and eat without knowing when to stop. If I have N portions of bird feed, how many pigeons will be fed with at least one portion of wheat?
checkio(3) == 2 checkio(5) == 3 checkio(10) == 6
💡Take a break and read the following ARTICLES. Who knows, maybe you will find new knowledge and ideas there!
Quick course in "generators" and "comprehensions" - This article is dedicated to the instruments, which you will use in almost every your solution! So make efforts to gain better understanding of them.
How to Get a List of All Files in a Directory With Python - Getting a list of all the files and folders in a directory is a natural first step for many file-related operations in Python. When looking into it, though, you may be surprised to find various ways to go about it.
A bit of humour at the end!
