ساختار شرطی در پایتون توجه داریم، که elif در جایی به کار می رود که بخواهیم مجددا شرط دیگری را بررسی کنیم. اگر بخواهیم برای تمام حالت های باقیمانده تصمیم بگیریم از else استفاده می کنیم. مثلا می خواهیم اگر اسم کاربر p1 یا p2 یا p3 بود پیام مناسب خود را دریافت کند و الا پیام خطا دریافت کند. حاصل چیزی شبیه زیر خواهد بود: user = "p9" if user=="p1": print("welcome p1") elif user=="p2": print("welcome p2") elif user=="p3": print("welcome p3") else: print("Error, Anonymous") #ساختار_شرطی #آموزش_پایتون

In general, many financial experts support their clients’ desire to buy cryptocurrency, but they don’t recommend it unless clients express interest. “The biggest concern for us is if someone wants to invest in crypto and the investment they choose doesn’t do well, and then all of a sudden they can’t send their kids to college,” says Ian Harvey, a certified financial planner (CFP) in New York City. “Then it wasn’t worth the risk.” The speculative nature of cryptocurrency leads some planners to recommend it for clients’ “side” investments. “Some call it a Vegas account,” says Scott Hammel, a CFP in Dallas. “Let’s keep this away from our real long-term perspective, make sure it doesn’t become too large a portion of your portfolio.” In a very real sense, Bitcoin is like a single stock, and advisors wouldn’t recommend putting a sizable part of your portfolio into any one company. At most, planners suggest putting no more than 1% to 10% into Bitcoin if you’re passionate about it. “If it was one stock, you would never allocate any significant portion of your portfolio to it,” Hammel says.
What is Telegram?
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
