Biror shart bajarish uchun if operatorlaridan foydalanishingiz mumkin va shart operatori deyarli barcha dasturlarda ishtirok etadi. Shart operatori 3 qismdan iborat (if, elif, else).
Kod bloklarini chegaralash uchun shart operatoridan pastki qism 4 ta bo'sh joy yoki 1 ta tabulyatsiyadan boshlanadi.
Agar ifoda rost bo'lsa shart operatori pastki qismidagi kod ishga tushadi, aks holda e'tiborsiz qoldiriladi.
x = 7 if x == 7: print("x 7 ga teng") x 7 ga teng
Shartlar bajarilishida birinchi if operatoridan foydalaniladi.So'ng elif yoki else operatorlaridan foydalanishingiz yoki foydalanmasligingiz mumkin.
Nima uchun elif operatori kerak? ⚠️ Agar hamma shartga if operatorini qo'llasak hamma shart operatorlari ishga tushadi.Agar birinchi shartga if shart operatori boshqa shartlarga elif shart operatoridan foydalansak elif shart operatori ishga tushsa qolgan operatorlar e'tiborsiz qoldiriladi.Quyidagi kodda 'x 18 ga teng' chop etilmadi sabab undan yuqoridagi elif operatori bajarildi.
x = 18 if x == 22: print("x 22 ga teng") elif x < 22: print("x 22 dan kichik") elif x == 18: print("x 18 ga teng") else: print("Yuqoridagi shartlar ishga tushmadi")
x 22 dan kichik
else shart operatori boshqa holatlarda ishga tushadi.
x = 18 if x == 22: print("x 22 ga teng") elif x < 11: print("x 11 dan kichik") elif x == 15: print("x 15 ga teng") else: print("Yuqoridagi shartlar ishga tushmadi")

n the U.S. people generally use Bitcoin as an alternative investment, helping diversify a portfolio apart from stocks and bonds. You can also use Bitcoin to make purchases, but the number of vendors that accept the cryptocurrency is still limited. Big companies that accept Bitcoin include Overstock, AT&T and Twitch. You may also find that some small local retailers or certain websites take Bitcoin, but you’ll have to do some digging. That said, PayPal has announced that it will enable cryptocurrency as a funding source for purchases this year, financing purchases by automatically converting crypto holdings to fiat currency for users. “They have 346 million users and they’re connected to 26 million merchants,” says Spencer Montgomery, founder of Uinta Crypto Consulting. “It’s huge.”
How Does Bitcoin Work?
Bitcoin is built on a distributed digital record called a blockchain. As the name implies, blockchain is a linked body of data, made up of units called blocks that contain information about each and every transaction, including date and time, total value, buyer and seller, and a unique identifying code for each exchange. Entries are strung together in chronological order, creating a digital chain of blocks. “Once a block is added to the blockchain, it becomes accessible to anyone who wishes to view it, acting as a public ledger of cryptocurrency transactions,” says Stacey Harris, consultant for Pelicoin, a network of cryptocurrency ATMs. Blockchain is decentralized, which means it’s not controlled by any one organization. “It’s like a Google Doc that anyone can work on,” says Buchi Okoro, CEO and co-founder of African cryptocurrency exchange Quidax. “Nobody owns it, but anyone who has a link can contribute to it. And as different people update it, your copy also gets updated.”
