对元组列表Python进行排序

# 示例元组列表
tuples_list = [(3, 'c'), (1, 'a'), (2, 'b')]

# 根据元组的第一个元素排序
sorted_list = sorted(tuples_list, key=lambda x: x[0])
print(sorted_list)  # 输出: [(1, 'a'), (2, 'b'), (3, 'c')]

# 根据元组的第二个元素排序
sorted_list_by_second_element = sorted(tuples_list, key=lambda x: x[1])
print(sorted_list_by_second_element)  # 输出: [(1, 'a'), (2, 'b'), (3, 'c')]

# 示例元组列表
tuples_list = [(3, 'c'), (1, 'a'), (2, 'b')]

# 根据元组的第一个元素排序
tuples_list.sort(key=lambda x: x[0])
print(tuples_list)  # 输出: [(1, 'a'), (2, 'b'), (3, 'c')]

# 根据元组的第二个元素排序
tuples_list.sort(key=lambda x: x[1])
print(tuples_list)  # 输出: [(1, 'a'), (2, 'b'), (3, 'c')]

# 示例元组列表
tuples_list = [(3, 'c', 2), (1, 'a', 3), (2, 'b', 1)]

# 根据元组的第二个元素和第三个元素进行排序
sorted_list = sorted(tuples_list, key=lambda x: (x[1], x[2]))
print(sorted_list)  # 输出: [(1, 'a', 3), (2, 'b', 1), (3, 'c', 2)]
