访问用户在python中输入的值的元组值中的元组

my_tuple = (1, 2, 3)

my_tuple = 1, 2, 3  # 省略括号也是有效的

nested_tuple = ((1, 2), (3, 4), (5, 6))

value = my_tuple[0]  # 获取第一个元素

inner_value = nested_tuple[1][0]  # 获取第二个元组的第一个元素，即3

nested_tuple = ((1, 2), (3, 4), (5, 6))

for inner_tuple in nested_tuple:
    print(inner_tuple)

# 输出每个内部元组
# (1, 2)
# (3, 4)
# (5, 6)

# 访问并打印每个内部元组的第一个元素
for inner_tuple in nested_tuple:
    print(inner_tuple[0])

# 输出每个内部元组的第一个元素
# 1
# 3
# 5

original_tuple = (1, 2, 3)
modified_tuple = original_tuple[:1] + (4,) + original_tuple[2:]
print(modified_tuple)  # 输出 (1, 4, 3)
