tuple_list = [('1','2'),('2','3'),('2','6')]
string = Point
Desired_List = [Point('1','2'),Point('2','3'),Point('2','6')]
我尝试过以下代码:
for x in tuple_list:
x.append("Point")
for x in tuple_list:
x + 'Point'
如何将开头的字符串附加到列表中的每个元组?
更新您的信息,我在x和y点的csv文件中有2列和数百行:
x y
1 3
2 4
我希望得到:
Points = [Point(1,3),Point(2,4),......]
答案 0 :(得分:0)
如果你需要字符串,这就是要走的路:
desired_list = []
for x,y in tuple_list:
desired_list.append(f"Point({x},{y})")
产生以下输出:
>>> print(desired_list)
['Point(1,2)', 'Point(2,3)', 'Point(2,6)']
就名称元组而言,您可以按照以下方式执行此操作:
from collections import namedtuple
Point = namedtuple('Point', ['x', 'y'])
tuple_list = [('1','2'),('2','3'),('2','6')]
desired_list = []
for x,y in tuple_list:
desired_list.append(Point(x, y))
相应的结果是:
>>> print(desired_list)
[Point(x='1', y='2'), Point(x='2', y='3'), Point(x='2', y='6')]
