如何根据Python匹配列表和字典

my_list = [1, 2, 3, 4, 5]
target = 3

for item in my_list:
    if item == target:
        print("Match found!")
        break

my_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
target_key = 'c'

for key, value in my_dict.items():
    if key == target_key:
        print("Key matched!")
        break

my_list = [1, 2, 3, 4, 5]
target = 3

try:
    index = my_list.index(target)
    print("Match found at index:", index)
except ValueError:
    print("Match not found")

my_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
target_key = 'c'

value = my_dict.get(target_key, "Key not found")
print("Value:", value)

my_list = [1, 2, 3, 4, 5]
target = 3

matched_elements = [item for item in my_list if item == target]
print("Matched elements:", matched_elements)

my_dict = {'a': 1, 'b': 2, 'c': 3, 'd': 4}
target_key = 'c'

matched_values = [value for key, value in my_dict.items() if key == target_key]
print("Matched values:", matched_values)
