The lambda function assigned to full_name takes two arguments and returns a string interpolating the two parameters first and last. As expected, the definition of the lambda lists the arguments with no parentheses, whereas calling the function is done exactly like a normal Python function, with ...

map(function, iterable) 使用lambda表达式将一个函数应用于可迭代对象中的每个元素,并返回一个由结果组成的新可迭代对象。 numbers = [1, 2, 3, 4, 5] squared_numbers = map(lambda x: x**2, numbers) print(list(squared_numbers)) # 输出:[1, 4, 9, 16, 25] filter(function, iterable) 使用...
