问题
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.
pseudo code:
tuple = (46, 153)
string = str(tuple)
ss = string.search()
int1 = first_int(ss)
int2 = first_int(ss)
print int1
print int2
int1 would return 46, while int2 would return 153.
回答1:
int1, int2 = tuple
回答2:
The other way is to use array subscripts:
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.

The third way is to use the new namedtuple type:
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 *:
a = (1,2,3)
b = [*a]
print(b)
it gives you a list
