Python--函數return多個值

# 函數如果有多個return值，那麼會把這幾個return值放到一個元組裡面返回

# def hello(a, b, c, d):
#     return a, b, c, d
#
# res = hello(‘abc‘, ‘ert‘, ‘qwe‘, ‘lkj‘)
# print(res)

# 列表推導式
nums = [0, 1, 3, 4, 5, 6, 7]
# nums = [‘0‘, ‘1‘, ‘3‘]將裡面int變為字串類型
new_nums = [str(x) for x in nums]
print(new_nums)

# 交換變數值
a = 1
b = 2
# a, b = b, a
# print(a, b)

# 針對整數，小數等可以用此方法，str不適用
a = a + b
b = a - b
a = a - b
print(a, b)
