for 语句会自动为你创建一个临时的未命名变量来保存迭代器,以便在循环期间使用。 简而言之,当你写for k in sequence: ... body ...时,for循环会询问sequence下一个元素,得到返回值后,将其命名为k,然后执行其主体。然后,for循环再次询问sequence下一个元素,再次将其命名为k,再次执行主体,依此类推,直到序列耗...

Let me show you an example of themultiplication of two numbers in Python.Here are two examples. To multiply two numbers in Python, you use the*operator. For instance, if you have two variablesaandbwherea = 5andb = 3, you can multiply them by writingresult = a * b. This will store...
>>> import math Hit enter, and you're done. Now in order to use thesin()function, go to a new line and type: >>> math.sin(3.14159) Since3.14159is approximately the value ofπhence the answer would be near to zero. As you can see aftermath.sin(3.14159)statement, the answer returne...
