python元组如何打包和解包

# 打包

a = 1, 10, 100

print(type(a), a)    # <class 'tuple'> (1, 10, 100)

# 解包

i, j, k = a

print(i, j, k)       # 1 10 100

a = 1, 10, 100, 1000

# i, j, k = a             # ValueError: too many values to unpack (expected 3)

# i, j, k, l, m, n = a    # ValueError: not enough values to unpack (expected 6, got 4)
