for i in range(5):
mylist[i]=int(input("Input an integer: "))
Do I really still have to define mylist before the for loop before I can actually use it? At the first loop it works fine but at the second loop it will show a NameError do I have to use a different inut method or what?
NameError: name 'mylist' is not defined
Yes, you need to define what "mylist" is before you assign values to it.
mylist = []
for i in range(5):
mylist.append(int(input("Input an integer: ")))
IndexError - set the size beforehand, i.e. mylist = [None] * 5
Yes, you have to define the list before like this
mylist=[]
for i in range(5):
mylist[i]=int(input("Input an integer: "))
IndexError unless the size of the list is declared beforehand. This can be circumvented by using .append(), thoughyou could just use list comprehension
mylist = [int(input("Input an integer: ")) for _ in range(5)]
You need to define mylist before you assign values to it.
mylist = [1, 2, 3, 4, 5]
for i in range(5):
mylist[i]=int(input("Input an integer: "))
Or if you want to fill the empty list use append() list function
mylist = []
for i in range(5):
mylist.append(input("Input an integer: "))
yes you are needed to define the list before the loop and also define the contents too, because it will throw a error Note: here i used 0 you can also use keyword None
myList = [0, 0, 0, 0, 0]
for i in range(5):
myList[i] = int(input("Enter a int: "))
or you could also use function append using this you don't have to define what does myList contains-
myList = []
for i in range(5):
myList.append(int(input("Enter a int: ")))
mylistahead of the loop or you'll getIndexErrorandNameErrorproblems
