如何检查单词是否在列表中，如果它存在于列表的项目中，则获取该项目的索引号

Question

我有一个名为A

的清单

A = ["How are you","I am good","What are you doing?"]

我想搜索一个单词“good”，如果在列表中找到它，那么我想得到项目的索引号，在该索引号中找到了单词。

期望的输出：

A = ["How are you","I am good","What are you doing?"]

B = "good"

结果=＆gt;

在列表A [1]

中找到了“好”字

我想获得找到该单词的列表项目的索引号。

Answer 1

试试这个（我做了一个功能）：

json_encode()

希望这有帮助！

Answer 2

你可以试试这个：

A = ["How are you","I am good","What are you doing?"]
B = "good"
d = [(i, a) for i, a in enumerate(A) if B in a]
print("Elements found", d[0][-1]) #printing what elements contain "good"
print("'{}' was found in list A[{}]".format(B, d[0][0]) if d else "'{}' not found".format(B))

输出：

'Elements found', 'I am good'
'good' was found in list A[1]
