creating sets of tuples in python
提问by Chung
How do i create a set of tuples with each tuple containing two elements? Each tuple will have an xand yvalue: (x,y)I have the numbers 1 through 50, and want to assign xto all values 1 through 50 and yalso 1 through 50.
如何创建一组元组，每个元组包含两个元素？每个元组都有一个xandy值：(x,y)我有 1 到 50 的数字，并且想要分配x1 到 50 以及y1 到 50 的所有值。
S = {(1,1),(1,2),(1,3),(1,4)...(1,50),(2,1)......(50,50)}
I tried
我试过
positive = set(tuple(x,y) for x in range(1,51) for y in range(1,51))
but the error message says that a tuple only takes in one parameter. What do I need to do to set up a list of tuples?
但是错误消息说一个元组只接受一个参数。我需要做什么来设置元组列表？
采纳答案by inspectorG4dget
mySet = set(itertools.product(range(1,51), repeat=2))
OR
或者
mySet = set((x,y) for x in range(1,51) for y in range(1,51))

tupleaccepts only one argument. Just explicitly write in the tuple instead using parentheses.
tuple只接受一个参数。只需在元组中明确写入而不是使用括号。
# vvvvv
>>> positive = set((x,y) for x in range(1,5) for y in range(1,5))
>>> positive
{(1, 2), (3, 2), (1, 3), (3, 3), (4, 1), (3, 1), (4, 4), (2, 1), (2, 4), (2, 3), (1, 4), (4, 3), (2, 2), (4, 2), (3, 4), (1, 1)}
