Choose without repetition:
You can use random.sample to avoid repetition:
indexes = random.sample(range(12), 12)
This will give you a list of 12 random indexes (from 0 to 11)
Adding to list:
Use append to add an item to list. (Whether item is a string or an integer)
group1.append(z[xy])
group1.append(x[xy]))
This will add z[xy] and x[xy] to the group 1 (As separate elements).
Formatting string:
If you want to have both student name and his/her level as one item, use string formatting.
group1.append("{} {}".format(z[xy], x[xy]))
"{} {}".format(z[xy], x[xy]) part will create a string by replacing {}s with items inside format input, respectively.
For example one result could be "Samuel 4"
Working code examples
Grouping with fixed size:
If size of each group should be exactly half (6), with fair skills, you can skip randomness. You can sort the students by their level and then starting from bottom add one to group one and one to group two and so one. (Or assign even numbers to group 1 and odd ones to group 2.
import random
class student:
def __init__(self, lvl, name):
self = lvl
self.name = name
Omer = student(3, "omer")
Michael = student(1, "Michael")
Sami = student(4, "sami")
Umar = student(5, "Umar")
Samuel = student(4, "Samuel")
Badmos = student(5, "Badmos")
Nabil = student(2, "Nabil")
Inacio = student(1, "Inacio")
Jesse = student(2, "student")
Ameerah = student(2, "Ameerah")
Bilal = student(2, "Bilal")
Joseph = student(2, "Joseph")
students = [Omer, Michael, Sami, Umar, Samuel, Badmos, Nabil,
Inacio, Jesse, Ameerah, Bilal, Joseph]
# Sort students by their level
students_sorted = sorted(students, key=lambda stu: stu.lvl)
# Create a list where each element contains a string of student name and level
students_with_names = ["{}: {}".format(stu.name, stu.lvl) for stu in students]
# Choose even ones for group1 and odd ones for group2
group1 = students_with_names[0::2]
group2 = students_with_names[1::2]
print(group1)
print(group2)
Grouping with variant size:
If group size is not important, you can shuffle students, then going over each student assign him/her to the group with lower sum of level.
