How do you split a list into evenly sized chunks in Python?
mylist = [1, 2, 3, 4, 5, 6, 7, 8, 9] I need to pass blocks of these to a third party API that can only deal with 4 items at a time. I could do one at a time but it's a HTTP request and process for each go so I'd prefer to do it in the lowest possible number of queries.
What I'd like to do is chunk the list into blocks of four and submit each sub-block.
So from the above list, I'd expect:
[[1, 2, 3, 4], [5, 6, 7, 8], [9]]

Using the * Operator The * operator can also be used to repeat elements of a list. When we multiply a list with any number using the * operator, it repeats the elements of the given list.
List is one of the simplest and most important data structures in Python. Lists are enclosed in square brackets [ ] and each item is separated by a comma. Lists are collections of items where each item in the list has an assigned index value. A list is mutable, meaning you can change its contents.
mylist = [1, 2, 3, 4, 5, 6, 7, 8, 9] print [mylist[i:i+4] for i in range(0, len(mylist), 4)] # Prints [[1, 2, 3, 4], [5, 6, 7, 8], [9]] If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
