This article is about how to use for statements in python. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Application scenario

1. When iterating over nested data types, for example, a list contains multiple dictionaries.

2. Whether there is a specified value in the demand judgment dictionary.

3. If so, prompt and exit the loop.

4. If it does not exist, we hope to get a unified prompt at the end of the whole cycle.

Example

Students = [{"name": "Ah Tu", "age": 20, "gender": True, "height": 1.7, "weight": 75.0}, {"name": "Xiaomei", "age": 19, "gender": False, "height": 1.6, "weight": 45.0} ] find_name = "Turkey" for stu_dict in students: print (stu_dict) # determine whether the name in the currently traversing dictionary is find_name if stu_dict ["name"] = = find_name: print ("found") # if it has been found If you just exit the loop, you don't need to compare the subsequent data break else: print (not found) print (loop over) Thank you for reading!
