When you write large numbers by hand, you typically group digits into groups of three separated by a comma or a decimal point. The number 1,000,000 is a lot easier to read than 1000000.In Python, you can’t use commas to group digits in integer literals, but you can use underscores ...
numbers = [1, 2, 3, 4, 5] squared_numbers = [num * num for num in numbers] print(squared_numbers) # [1, 4, 9, 16, 25] 推导式不仅列表能用,字典、集合、生成器也能使用。 下面看一下,使用字典推导式,将字典的值提高一倍。 dictionary = {'a': 4, 'b': 5} squared_dictionary = {...
