如何获得数组的索引？

Question

你好，我有这个代码：

a = ["aze", "1213", "fdpe"]
a+= ["dsf"] # I would want to get the index of this writting
something which allows to get the index because sometimes
it can be a variable and I cannot to know the value of the variable
a+= ["fsdfsd"]

我想获取此索引，例如，我想获取3，因为在我的cas a[3] = "dsf"

中

您有任何想法吗？

非常感谢您！

要获取python列表中对象的索引，可以使用list.index函数：

idx = list.index("dsf")   # idx = 3 in your example
