How do I get integers from a tuple in Python?
提问by rectangletangle
I have a tuple with two numbers in it, I need to get both numbers. The first number is the x-coordinate, while the second is the y-coordinate. My pseudo code is my idea about how to go about it, however I'm not quite sure how to make it work.
我有一个包含两个数字的元组，我需要得到两个数字。第一个数字是 x 坐标，而第二个数字是 y 坐标。我的伪代码是我关于如何去做的想法，但是我不太确定如何使它工作。
pseudo code:
伪代码：
tuple = (46, 153)
string = str(tuple)
ss = string.search()
int1 = first_int(ss)
int2 = first_int(ss)
print int1
print int2
int1would return 46, while int2would return 153.
int1将返回 46，而int2将返回 153。

int1, int2 = tuple

The other way is to use array subscripts:
另一种方法是使用数组下标：
int1 = tuple[0]
int2 = tuple[1]
This is useful if you find you only need to access one member of the tuple at some point.
如果您发现在某个时刻只需要访问元组的一个成员，这将非常有用。

The third way is to use the new namedtuple type:
第三种方法是使用新的 namedtuple 类型：
from collections import namedtuple
Coordinates = namedtuple('Coordinates','x,y')
coords = Coordinates(46,153)
print coords
print 'x coordinate is:',coords.x,'y coordinate is:',coords.y

a way better way is using *:
更好的方法是使用*：
a = (1,2,3)
b = [*a]
print(b)
it gives you a list
它给你一个清单
