Buat, indeks, dan iris sebuah tuple

Anda telah melihat bahwa salah satu perbedaan utama antara tuple dan struktur data lain seperti vektor adalah sifat tuple yang tidak dapat diubah (immutable). Pembuatan tuple sangat mirip dengan vektor, dan pengindeksan serta pengirisan (slicing) juga akan familier bagi Anda, menggunakan notasi kurung siku.

Dalam latihan ini, Anda akan membuat, mengindeks, dan mengiris sebuah tuple yang akan Anda beri nama emergency_information. Tuple ini harus memuat tiga isian yang Anda identifikasi pada pertanyaan sebelumnya sebagai data yang baik untuk disimpan dalam sebuah tuple.

Untuk membuat tuple, ingat bahwa Anda perlu menggunakan tanda kurung () untuk menampung nilai-nilai yang ingin Anda simpan dalam tuple.

Untuk mengindeks dan mengiris tuple, gunakan notasi kurung siku [] setelah nama tuple. Pengindeksan dimulai dari 1 untuk elemen pertama di Julia.

Loops are one of the core concepts that underpin Julia. In this chapter, you'll learn about for loops and while loops, and how to use them to iterate over data structures that you are already familiar with. You will also cover ranges, a useful tool for generating sequences of data.

Exercise 1: For loops Exercise 2: For loops question Exercise 3: Loop over a vector Exercise 4: Loops and enumerate Exercise 5: Looping over nested structures Exercise 6: While loops Exercise 7: Writing a while loop Exercise 8: While loops for iteration Exercise 9: Ranges Exercise 10: Ranges - iteration Exercise 11: Defining ranges Exercise 12: Looping over ranges Exercise 13: Splat unpacking

This chapter focuses on expanding your knowledge of the data structures available in Julia. Learn how to use tuples, dictionaries, multi-dimensional arrays, and structures to store and traverse data quickly and efficiently.

In this chapter, you’ll extend your understanding of functions, exploring positional, keyword, and default function arguments. You will also cover code execution timing, getting a strong understanding of how to measure the time your code takes to run. This chapter will round off with a capstone on writing your own functions to solve real-world problems.
