you may have solved 99% of the problem; In addition, when you ask a question before you need to search for yourself, and then describe your problem in detail, (questioning template bootcamp has to provide oh ~), so that the answer to your This is a sign of respect for the person ans...

Coding Practice Q3: Lambdas and Currying 我们可以把一个多个参数的函数转化成一系列高阶的单个参数的函数,这也是lambda表达式的优势所在。在处理单个参数的函数时,这非常有用,之后我们将会有一些样例来展示这点。 编写函数lambda_curry2,它可以用lambda表达式curry任意两个参数的函数。你可以看一下下面的测试案例,...
There are many ways of solving this problem: # Note: :list and -> bool are just python typings, they are not needed for the correct execution of the algorithm. Taking advantage of sets and len: def is_unique(l:list) -> bool: return len(set(l)) == len(l) This one is can ...

Loops and iteration complete our four basic programming patterns. Loops are the way we tell Python to do something over and over. Loops are the way we build programs that stay with a problem until the problem is solved. 循环和迭代完成了我们的四种基本编程模式。循环是我们告诉Python一遍又一遍地...
