交換兩個數順序

a,b = b,a

同時判斷多個標誌位

a, b, c = 0, 1, 1

if 1 in (a, b, c):
    print("passed")

if any((a, b, c)):
    print('passed')

if a or b or c:
    print('passed')

合併兩個列表

x = {'a': 1, 'b': 2}
y = {'b': 3, 'c': 4}
z = {**x, **y}
print(z)

列表逆序輸出

a = [1,12,3,2,3]
b = 'adfa'
print(a[::-1])
print(b[::-1])

print (list(reversed(a)))
print (list(reversed(b)))
