This is example of "type error". That is Python can't recognize the kind of information you're using
To be able use integers within string we need explicit specification.

list and perform the same task with each item. For example in a list of numbers you want to perform the same statistical operation on every element.Students = ['Muhammad Abdullah',"Kayli Abernathy","Jacqueline Alvarez","Lainey Bourgeois","Garrett Carr","Chance Chapman"]
for student in Students:
print (student)
Python initially reads the first line of the loop.
This line tells Python to go into list Students and retrieve first element and store it in the variable "student". The first student is "Muhammad Abdullah". Then Python reads the next line:
Python prints the first value of "student". Because the list contains more values, PYTHON returns to the first line of the loop. PYTHON repeats the same purcedure until no more items remains in the list.
Note: for building loops you can use any name instead of student.
for student in Students:
print (student.title() +" is a good student")
names = str()
for student in Students:
names += student +" ,"
print("Our MAB students are " + names)
range() function makes it easy to deal with numbers.for value in range(1,6):

square = number**2
squares.append(square)
print(squares)
min(squares)
max(squares)
sum(squares)
for loop code more concise and more efficient when dealing with lists. The answer is yes. We need to use list comprehension.squares = [number**2 for number in range(1,11)]
print (squares)

IF statement helps to exemine current state of a program and respond appropriately to that state.Students = ['Muhammad Abdullah',"Kayli Abernathy","Jacqueline Alvarez","Lainey Bourgeois","Garrett Carr","Chance Chapman"]

if name in Students:
print (name + " is MAB student")
uppercase.title case.Important: for conditional statements you need to use "==" equality operator, which returns True if the values on the left and right side of the operator match, and False if they don't.
requested_course = "Agec 619"
if requested_course != "Agec 622":
print ("Request Another Course")
!= operator compares if requested_course is equal to the value "Agec 622". If these two value do not match Python returns True.########TRY TO ANSWER############

"for loop" takes a collection of items and executes a block of code once for each item in the collection. In contrast, the while loop runs as long as, a certain condition is true.current_number = 0
