In Tkinter, Canvas.create_line() method is used to create lines in any canvas. These lines can only be seen on canvas so first, you need to create a Canvas object and later pack it into the main window.
 

Syntax: 

Canvas.create_line(x1, y1, x2, y2, ...., options = ...)


Note: Minimum of 4 points are required to create a line, but you can also add multiple points to create different drawings.
Class parameters:
 

Data members used: 
master 
canvas
Member functions used for the given class: create() method
Widgets used: Canvas
Tkinter method used: 
canvas.create_line() 
pack() 
title() 
geometry() 
 


Below is the Python code - 
 

Python3
# Imports each and every method and class  # of module tkinter and tkinter.ttk from tkinter import * from tkinter.ttk import * class GFG: def __init__(self, master = None): self.master = master # Calls create method of class GFG self.create() def create(self): # This creates a object of class canvas self.canvas = Canvas(self.master) # This creates a line of length 200 (straight horizontal line) self.canvas.create_line(15, 25, 200, 25) # This creates a lines of 300 (straight vertical dashed line) self.canvas.create_line(300, 35, 300, 200, dash = (5, 2)) # This creates a triangle (triangle can be created by other methods also) self.canvas.create_line(55, 85, 155, 85, 105, 180, 55, 85) # This pack the canvas to the main window and make it expandable self.canvas.pack(fill = BOTH, expand = True) if __name__ == "__main__": # object of class Tk, responsible for creating # a tkinter toplevel window master = Tk() geeks = GFG(master) # This sets the title to Lines master.title("Lines") # This sets the geometry and position of window # on the screen master.geometry("400x250 + 300 + 300") # Infinite loop breaks only by interrupt master.mainloop() 

Output: 
 

Example 2: For filing color in the shapes.

Python3
from tkinter import * root=Tk() root.title("canvas line") root.geometry("555x555") our_canvas=Canvas(root,width=300,height=200,bg="white") our_canvas.pack() #creating rectangle our_canvas.create_rectangle(50,150,250,50,fill="blue") root.mainloop() 

Output:
