Lists support the use of the operators \(+\) and \(*\). These operators work similar as to how they work for strings.
You can add two lists together with the \(+\) operator, the result of which is a list which contains the elements of both lists involved. Of course, you have to assign the result to a variable to store it.
You can multiply a list by a number to create a list that contains the elements of the original list, repeated as often as the number indicates. This can be a fast approach to create a list with all equal elements.
fruitlist = ["apple", "banana"] + ["cherry", "durian"]
print( fruitlist )
numlist = 10 * [0]
print( numlist )
Note: With the \(+\) you can add a list to another list, but you cannot add a new element to a list, unless you turn that new element into a list with a single element by putting two square brackets around it. If you try to add something to a list that is not a list, Python will try to interpret it as a list – if it can do that (which it can, for instance, for a string, which it can consider a list of letters); it will then still do the addition but the result will not be what you want. For instance, the code below tries to add a “cherry” to a list, but only the second addition actually does what is intended.
fruitlist = ["apple", "banana"]
fruitlist += "cherry"
print( fruitlist )
fruitlist = ["apple", "banana"]
fruitlist += ["cherry"]
print( fruitlist )
