Any suggestions for this code?

I'm trying to prompt the user for coordinates in the following matter, but it is not working. Any advice would be great. Thank you all for your time in advance.

[x1, y1] = input('Please enter the first coordinates in this form [# #]: ');

[x2, y2] = input('Please enter the second coordinates in this form [# #]: ');

[x3, y3] = input('Please enter the third coordinates in this form [# #]: ');

 tmp = input('Please enter the first coordinates in this form [# #]: ');
 x1=tmp(1);
 y1=tmp(2);

and so on...
