我试图编写一个解析例程并使用该find函数。但无论我搜索什么，它总是给我一个 -1。

doc_list = ["The Learn Python Challenge Casino.", "They bought a car", "Casinoville"]

for word in doc_list:
    word.upper()
    word.find("A")

输出：

doc_list = ["The Learn Python Challenge Casino.", "They bought a car", "Casinoville"]

for word in doc_list:
    word.upper()
    word.find("A")
