Python - How to put tuples into a single list?

I have variables of tuples:

student1 = ("Allan", "Anderson")
student2 = ("Barry", "Byars")
brendan = ("Brendan","Smith")
sandy = ("Sandy","Garner")

I want to put them in a list:

students = [("Allan", "Anderson"),("Barry", "Byars")]

How would you do this? I have 7 variables of tuples and is there an efficient way to do this?

I know students.append() can do it but because I have 7 variables, is there a faster way?

You should use a better data structure here (like a dictionary) :

Students = {
    "student1": ("Allan", "Anderson"),
    "student2": ("Barry", "Byars"),
    "brendan": ("Brendan", "Smith"),
    "sandy": ("Sandy", "Garner")
}

StudentList = [student for student in Students.values()]
print(StudentList)

Output

[('Allan', 'Anderson'), ('Barry', 'Byars'), ('Brendan', 'Smith'), ('Sandy', 'Garner')]

In this way, if you want to add another list you just have to add a single line in your dictionary without changing any logic :

Students["JohnDoe"] = ("John", "Doe")

Output :

[('Allan', 'Anderson'), ('Barry', 'Byars'), ('Brendan', 'Smith'), ('Sandy', 'Garner'), ('John', 'Doe')]

The simple way to achieve this can be,

student1 = ("Allan", "Anderson")
student2 = ("Barry", "Byars")
student = [student1, student2]

print(student)

You can define your variables as a dictionary where the keys are the names of the variables.

For example:

vars_dict = {
"student1": ("Allan", "Anderson"),
"student2": ("Barry", "Byars")
}

and then using dict's values() method get all values as a list:

students = list(vars_dict.values())

If there's no structure to your variable names, this is the easiest way.

students = [student1, student2, brendan, sandy]

[('Allan', 'Anderson'), ('Barry', 'Byars'), ('Brendan', 'Smith'), ('Sandy', 'Garner')]
