Although we commonly use train_test_split on one or two input arrays (Xandy), technically, the function will operate on multiple arrays. If you need to split many arrays, you can provide them in addition toXandy. test_size Thetest_sizeparameter enables you to specify the size of the outpu...
Pandas, a powerful data manipulation library in Python, can also be used for splitting strings on multiple delimiters. Itsstr.split()function is capable of handling regex, making it another effective tool for this task. While the built-in string methods are efficient for smaller data, when you...
