✅لیست ها در پایتون(4)

⏪حالا میخواهیم یک مثال برای لیست دو بُعدی با استفاده از حلقه for بزنیم:
میخواهیم یک لیست دو بُعدی شامل اعداد یک بنویسیم و هر بُعد لیست 5 عنصر داشته باشد،اول کد رو ببینید:

»> array1 = [[1 for j in range(5)] for i in range(2)]
»> array1
[[1, 1, 1, 1, 1], [1, 1, 1, 1, 1]]

در مثال فوق از دو حلقه for استفاده کردیم اولین حلقه تعداد عناصر در هر بُعد رو نمایش میده(5) و دومین حلقه هم تعداد ابعاد رو(2) نمایش میده،توجه کنید که حلقه اول مجزا داخل یک کروشه قرار میگیره ولی حلقه دوم فقط داخل کروشه اصلی قرار میگیره

⏪حالا برای ایجاد یک لیست سه بعدی کافیه حلقه دوم رو که تعداد ابعاد نمایش میده عدد سه قرار بدهیم.و ابعاد دیگر هم به همین صورت فقط عدد فانکشن range حلقه دوم تغییر میکنه و همیشه حلقه for ما دوتاست.

⏪حالا یک نکته مهمی که وجود داره، ما تو آموزش مقدماتی گفتیم که از تابع type میاییم نوع عناصر رو مشخص میکنیم،حالا لیست های که تا اینجا گفتیم پایتون ، به چه نوعی میشناسه؟؟؟بیاییم تست کنیم:

»> type(array1)
<type 'list'>

همانطور که در بالا مشاهده میکنید نوع رو بصورت لیست نمایش میده که ما هم چنین انتظاری هم واقعا داشتیم.ولی اگر لازم باشه من حتما بخواهم از نوع آرایه داشته باشم باید چیکار کنم؟

ما در بخش بعدی آموزشون ابزاری رو بهتون معرفی میکنیم که این امکان برای ما به وجود بیاره که بتونیم مقادیری از نوع خود آرایه داشته باشیم و اولین ابزاری که بهتون معرفی میکنیم ابزار numpy هست.این کتابخانه کارایی بسیار بالایی در پایتون داره و اساساً این ابزار نحوه دسترسی جدیدی برای ماتریس ها و آرایه ها برای ما فراهم میکنه.پس در بخش بعدی با همراه باشید....

Follow the instructions below to do so on both mobile and PC. Open the Telegram mobile app (Android | iOS) and locate the convo you wish to archive, but don’t tap on it. Long-press it until you see a green checkmark appear next to the contact’s profile picture. A few buttons will show up in the upper-right corner as well. Select the “Archive” icon.On PC, you’ll need to right-click on the conversation on the right side of the display and select the “Archive” option.

Telegram Q&A

Q: How does hottg.com work?

Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.

What's more, there is no need to worry about disk space on your device. With Telegram's cloud support and cache management options, Telegram can take up nearly zero space on your phone.

Q: How is Telegram different from WhatsApp?
