This comprehensive guide explores Python'stuplefunction, which creates immutable sequence objects. We'll cover creation, conversion from other iterables, and practical examples of using tuples in Python programs
tuple built-in function tuple tips: 1.对于Python中的tuple类型来说,他与其它的序列类型来讲最大的不同就是tuple是不可变的。 2.当你需要创建一个只有一个元素的tuple时,需要在元祖分隔符里面加一个逗号(,) 3.tuple只有两个built-in function,一个是count,一个是index。作用和列表类似。这里就不一一赘述了 ...

The join function in python is a built-in method that allows us to join the elements of a list or tuple into a single string.
In [7]: p=['kzc',18]In [8]: '{0[0]},{0[1]}'.format(p)Out[8]: 'kzc,18' 有了这些便捷的“映射”方式,我们就有了偷懒利器。基本的python知识告诉我们,list和tuple可以通过“打散”成普通参数给函数,而dict可以打散成关键字参数给函数(通过和*)。所以可以轻松的传个list/tuple/dict给format函...
