stack and crashing Python. The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a ...
Explore Program Creating a Tuple in Python A Python tuple is created using parentheses around the elements in the tuple. Although using parentheses is only optional, it is considered a good practice to use them. Elements in the tuple can be of different data types or of the same data type...
