Programming problem: the existing 100 student achievement, achievement as an integer (0-100), for rank statistics the number of each level and output statistics results: one is divided into five grades, more than 90 points for the best; 80 ~ 89 was divided into good; 70 ~ 79 were divided into medium; 60 ~ 69 divided into pass; Below 60 points for the fail,

Implementation steps are as follows:

1, the random Numbers produced 100 student achievement and put them in a list

2, the achievements of the list of statistics, statistical results in the dictionary (function)
Among them to implement a function to convert a single score to rank

3, output the results in the dictionary

Import the random
The from the collections import Counter

Def do_level (study) :
If study & gt;=90:
Return "good"
Elif 80 & lt;=study & lt;=89:
Return "good"
Elif 70 & lt;=study & lt;=79:
Return "medium"
Elif 60 & lt;=study & lt;=69:
Return "pass"
Elif study & lt; 60:
Return "fail"

Def get_all_study_info () :
Class_int_list=list ()
Class_study_list=list ()
For I in range (100) :
Stud_class=random. Randint (0100)
Class_int_list. Append (stud_class)
Print (" this is the list of student performance output: {} ". The format (class_int_list))
For I in class_int_list:
Study=do_level (I)
Class_study_list. Append (study)
# print (class_study_list)
Return class_study_list

Def the main () :
Class_study_list=get_all_study_info ()
Study (class_study_list)=Counter # statistical functions, the list of statistics the number of occurrences of each element in the
Print (" this is the student achievement dictionary output: {} ". The format (dict (study))

If __name__=="__main__ ':
The main ()

Thank you???????? !
