How to move to a different section of code - python-3.7

Question

new python programmer, looking for a fix for this issue. I'm making an autofill rubric for a school project, how would I move to a different section of my code. For example, I want to be able to re-run this function, but that breaks my input because I cannot put it into the function itself.
#TODO...
#Add students names in IN the code, same with num of students
numberOfStudents = 4
rubrick = ["Preparedness", "Engagement", "Perseverance", "Problem Solving", "Progessionalism"]
students = ["ROBERT", "DEVIN", "SKYLER", "XAVIER"]
def pickStudent():
print('Please select your student...')
for x in range(len(students)):
print(students[x])
pickStudent()
userPicked = input().upper()
if userPicked == students[0]:
print("You picked... " + students[0])
elif userPicked == students [1]:
print("You picked... " + students[1])
elif userPicked == students [2]:
print("You picked... " + students[2])
elif userPicked == students [3]:
print("You picked... " + students[3])
else:
print("Invalid user... \n")
pickStudent()
userPicked = input().upper()
Any help would be apreciated.

Answer 1

A few things to pick out here.
You probably want to put the user picking in a while loop to ensure it keeps asking until a correct answer is given.
You also don't need to test the entry against each item in the list in turn - instead use the in operator to see if the inputted text is found ion the list.
Combining these gives you:
while userPicked not in students:
userPicked = input().upper()
Instead of looping over students to print them, you can write neater code using join - to join all the items in the students list into a string and print that:
print('\n'.join(students))
