Начиная с Python 3.5, стало возможно использовать распаковку в литералах словарей и списков.

Пример со словарём:


{**{'a': 1}, 'b': 2, **{'c': 3}}
# Результат: {'a': 1, 'b': 2, 'c': 3}


Пример со списком:


[1, 2, *[3, 4]]
# Результат: [1, 2, 3, 4]


Для словарей такая форма даже мощнее, чем функция dict, потому что позволяет переопределять значения:


{**{'a': 1, 'b': 1}, 'a': 2, **{'b': 3}}
# Результат: {'a': 2, 'b': 3}

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.

Telegram hopes to raise $1bn with a convertible bond private placement

The super secure UAE-based Telegram messenger service, developed by Russian-born software icon Pavel Durov, is looking to raise $1bn through a bond placement to a limited number of investors from Russia, Europe, Asia and the Middle East, the Kommersant daily reported citing unnamed sources on February 18, 2021.The issue reportedly comprises exchange bonds that could be converted into equity in the messaging service that is currently 100% owned by Durov and his brother Nikolai.Kommersant reports that the price of the conversion would be at a 10% discount to a potential IPO should it happen within five years.The minimum bond placement is said to be set at $50mn, but could be lowered to $10mn. Five-year bonds could carry an annual coupon of 7-8%.
