Python教程-Python将元组解压缩为变量或参数 ^原

1. Python解压元组示例

1.1。解压示例– 1

$title(example1.py)
>>> data = (1, 2, 3)
>>> x, y, z = data
>>> x
1
>>> y
2
>>> z
3

1.2。解压示例– 2

$title(example2.py)
>>> data = [ 'Lokesh', 37, 73.5, (1981, 1, 1) ]
 
>>> name, age, weight, dob = data
 
>>> name
'Lokesh'
>>> dob
(1981, 1, 1)
 
# Another Variation
 
>>> name, age, weight, (year, mon, day) = data
 
>>> name
'Lokesh'
>>> year
1981
>>> mon
1
>>> day
1

1.3。解压示例– 3

$title(example3.py)
>>> greeting = 'Hello'
 
>>> a, b, c, d, e = greeting
 
>>> a
'H'
>>> b
'e'
>>> c
'o'

2.开箱时可能出现的错误

$title(example4.py)
>>> p = (4, 5)
 
>>> x, y, z = p
