running life cycle of a program can be divided into 4 stages: compile-time, link-time, load-time, run-time. In Python, these 4 phases are one, but strictly separate in C #, which requires reflection in C # to perform across stages. This has resulted in a great difference between the two;4. Python can quickly switch between types, whereas C # needs to be implemented by the corresponding type conversions;5.

the stop iteration. In Python, many objects can be traversed directly through a for statement, such as list, String, Dict, and so on, which can be called an iterative object. As for which objects can be accessed iteratively, it is necessary to understand the knowledge of iterators.IteratorsThe iterator object requires an object that supports the iterator protocol, in Python, the __iter__ () and Next () met
