Question

如何为列表verbs中的每个动词添加“ ing”？如果要在每个单词后加上“ ing”（例如“皮划艇，哭泣...”）到新列表中，那很容易，但我不知道如何用“皮划艇，哭泣，走路”来覆盖原始动词列表。 ..“

我不相信追加是正确的方法，因为这只是将每个单词对象添加到动词列表的末尾。谢谢大家。

verbs = ["kayak", "cry", "walk", "eat", "drink", "fly"]

for words in verbs:
    words = words + "ing"

Answer 1

您可以使用列表理解：

verbs = ["kayak", "cry", "walk", "eat", "drink", "fly"]
verbs = [words + "ing" for words in verbs]

Answer 2

如果您特别需要使用for循环，最简单的方法是使用列表的索引，如下所示：

for i in range(len(verbs)):
    verbs[i] += 'ing'

Answer 3

var objectCollection = [];
var o = {}

o.foo = 1;
objectCollection.push(o);

o.foo = 2;
objectCollection.push(o);


console.log(objectCollection)    //All 2 elemets are the same object

objectCollection[0].foo = 100;
console.log(objectCollection);

Answer 4

verbs = ["kayak", "cry", "walk", "eat", "drink", "fly"]
ing=[]
for i in range(len(verbs)):
    ing.append(verbs[i]+"ing")

print(ing)
