The empty result of a program written in python

hello,

suggestion:

import pandas as pd import requests import numpy as np import json # Send a GET request to retrieve the list of student IDs from the endpoint student_list = [1] for ID in student_list: response = requests.get(f"https://examen-api.s3.eu-west-1.amazonaws.com/Student/{ID}") student_info = response.json() print(student_info['StudentName']) 

Thank you for your response.

However, it shows me only one student with 1.

To display all the students, please? Do we need to increment the list?

Thanks.

What is requested is to manage a unique one, that’s why I tried result = df.groupby('Student')['ID'].nunique(), which returns nothing:

The endpoint to use is ""https://examen-api.s3.eu-west-1.amazonaws.com/Student/{ID}"" where {ID} corresponds to the identifier of a student.

Tips:

• Do not define the function right away. First, develop a set of instructions to handle a single student, then generalize your approach in a loop that iterates through a list of identifiers, and finally define the function.
• The simplest way to proceed is to instantiate a DataFrame from a list of dictionaries in the following form:

Already:

student_list = [] for ID in student_list:

For me, as long as student_list is not filled, you can do all the loops you want, it will finish quickly!

I would start with an HTTP GET to get the list filled.

See you later blux "Fools dare everything.
That's how we recognize them."

Hello,

There are several things that are not right:

• The statement is incomplete: what attributes do you want to retrieve given one (or more) student identifiers? Their name?
  • This would likely clarify why you are using groupby and nunique.
• Your list student_list (which I would rather call student_ids) is not populated. At the same time, I would rename ID to student_id, that would be clearer. Indeed, in Python, variable names in capital letters are reserved for global "constants."
• The attribute name containing the identifier in your DataFrame is not ID, but StudentID. To realize this, you just need to look at what returns https://examen-api.s3.eu-west-1.amazonaws.com/Student/1
  • Example:

    { "StudentID": 1, "StudentName": "David Williams", "StudentCursus": "DA", "StudentCourses": [ 4, 2, 1, 3 ] }

• While developing your program, you should add a print statement after each instruction to see its result. This would allow you to see the state of each variable and better understand what is happening.
• Any modules you explicitly use. In your case, you import numpy and json but you do not use them. To avoid this kind of error, you can use flake8:
• This is not fundamental, but at the beginning of the file, there is a missing shebang. It would be nice to add it to make your script executable.

Assuming we want to retrieve the names of the students:

#!/usr/bin/env python3 import pandas as pd import requests student_ids = range(3) for student_id in student_ids: url = f"https://examen-api.s3.eu-west-1.amazonaws.com/Student/{student_id}" response = requests.get(url) student_ids = response.json() df = pd.DataFrame(student_ids) print(df) resultat = df["StudentName"][0] print(resultat)

Good luck
