Learn how to use a split to break a string into a list or array.
- [Voiceover] The split function is used to split a string…into an array of parts, using regular expressions,…and if I go ahead and run this, you'll see that it splits…this string up into an array, and displays each…of the words separately from the array,…and so split takes a regular expression as…its first argument, and then the string as…its second argument, and it returns a list which can be used…to initialize an array or I could even just take that…and put it right at the,…in the for each, and run it, and we get exactly…the same result.…
Where this comes in handy is things like,…for example an IP address, if I have…18.104.22.168,…and I wanna split on the period, now the period of course…is a wildcard character, so if I wanna use a literal period…I have to put a backslash before it, and I run that,…and now I have the parts of my IP address,…all in separate convenient strings in a list,…or for example, let's say I had a string that had…a bunch of different values separated by colons.…
Value:another,…yet another, and one more here,…
