循环遍历嵌套数组并查找索引号

Question

array = [     
              ["Bitcoin", "Bitcoin"],
              ["Ethereum", "Bitcoin"],
              ["XRP", "Bitcoin"],
        ]

我想搜索关键字“以太坊”，并输出数组中位置的索引（2）。 现在，它将显示嵌套数组（0）的数组中的位置

for counter in subreddits:
  #subredditIndex = counter.index("Ethereum")
    try:
        print(counter.index("XRP"))
        # print(counter[0])
        # print(type(counter[0]))
    except:
        print("No string found")

Answer 1

您需要跟踪外部索引

etherium_index = None
for i in range(0, len(myList)):
    if myList[i][0] == 'Etherium':
        etherium_index = i
