In Python, you can get the sum of all integers in a list by using the sum method: sum = sum([1, 2, 3, 4, 5]) print(sum) # 15 However, this does not work on a list of integer strings: #
list3 = list(["red", "green"]) list4 = list(range(3, 6)) #[3, 4, 5] list5 = list("abcd") #['a', 'b', 'c', 'd'] 1. 2. 3. 4. 5. 上面的表达式可以使用更简单的语法表示: list1 = [] list2 = [2, 3, 4] list3 = ["red", "green"] list4 = [2, "three"...
