获取某个值为python的数组的索引

# 示例列表
my_list = ['apple', 'banana', 'cherry', 'date', 'apple']

# 使用 index() 方法获取 'apple' 的第一个索引
try:
    index = my_list.index('apple')
    print(f"The first index of 'apple' is: {index}")
except ValueError:
    print("The value is not in the list.")

# 使用 enumerate() 函数遍历列表并打印所有 'apple' 的索引
for i, value in enumerate(my_list):
    if value == 'apple':
        print(f"Found 'apple' at index: {i}")

if 'apple' in my_list:
    index = my_list.index('apple')
    print(f"The first index of 'apple' is: {index}")
else:
    print("The value is not in the list.")

indices = [i for i, value in enumerate(my_list) if value == 'apple']
print(f"All indices of 'apple': {indices}")
