coeff = input('Please enter the coefficients for the polynomial of the form ax^2 + bx + c = 0. Input all three values in this form [a b c] If a term is missing, use zero as a placeholder Input values (include square brackets): ');

this is an input function that tells the user to input 3 variables but as you can see this is very long and when i run it it displays this whole thing on one line

I need to display this on multiple lines in the command window i have tried doing ... but it has failed

Use \n inside you string to have a newline

Example:

input(['Please enter the coefficients for the polynomial of the form ax^2 + bx + c = 0.',...
       '\nInput all three values in this form [a b c].',...
       '\nIf a term is missing, use zero as a placeholder.',...
       '\nInput values (include square brackets): '])

Note that I broke the string for better readability. For instance if you remove the \n, even if you have on different lines in the editor, it will still be a single line in the command window.
