How to use For loop to print all items in python class












-1















I have created a new class:



testing.py:



class student:
def __init__(self, name, major, gpa):
self.nm = name
self.mj = major
self.gp = gpa


then, I move to my working file testing.py:



from testing import student
student1=student("Marcos","Physics",3.99)
student2=student("Phillyp","Biology",2.99)
student3=student("Naim", "Architecture", 3.42)

for k in range(1,4):
print(student(k).gp) <------- how do I merge this string with int!?!?


my final aim is to print out ALL the gpa of all students, so I know I need to do



print(student1.gp)
print(student2.gp)
print(student3.gp)


So how can I concatenate the k into the variable name to produce student1.gp, student2.gp etc?



Thank you all so much!

instead of this for k in range(1,4): you want to iterate over a list of all of your students:



students = [student1, student2, student3]
for student in students:
print(student.gp)


EDIT



If you want to be able to reference the students by name, store them in a dict:



students = {'student1': student("Marcos","Physics",3.99),
'student2': student("Phillyp","Biology",2.99),
'student3': student("Naim", "Architecture", 3.42)}

for i in range(1, 4):
print(students[f'student{i}'].gp)
# if less than python 3.6
# print(students['student{}'.format(i)].gp)

  • thanks for the suggestion, but my ultimate aim is to know how to concatenate that k (integer) into "student" (is this considered a string?)

  • @MT32 No it's not a string, it's a variable name. I would highly recommend you use a list to store your students.
