Using List Comprehension with Fixed-Length Sublists When you have sublists of the same length, you can use list comprehension to unpack and add new values ? data = [[10, 20], [14, 8], ['Mon', 'Tue']] print("Given List:") print(data) s = "Rise" t = "fast" result = [[m, n, s, t] for m, n in data] print("New List:") print(result) ...
Read MoreTurtle graphics using Python
Python's Turtle graphics library provides an easy way to create drawings and animations. After importing turtle, you can use commands like forward(), backward(), right(), and left() to move the turtle cursor and draw shapes. By combining these commands, you can create beautiful graphics ranging from simple shapes to complex patterns. Simple Turtle Commands forward(10) − Moves the turtle forward by 10 pixels backward(5) − Moves the turtle backward by 5 pixels right(35) − Turns the turtle clockwise by 35 degrees left(55) − Turns the turtle counter-clockwise by 55 degrees goto(x, y) − Moves the turtle to position ...

Read MorePython - Get the Index of first element greater than K
When working with Python lists, you often need to find the index of the first element that satisfies a specific condition. In this article, we'll explore different methods to get the index of the first element greater than a given value K. Using Enumeration with next() The enumerate() function provides both the index and value of each element. Combined with next(), it returns the first index where the condition is met ? numbers = [21, 10, 24, 40.5, 11] K = 25 print("Given list:", numbers) # Using next() + enumerate() result = next(k for k, ...

Read MorePython - Get sum of tuples having same first value
Tuples are Python collections that are ordered but unchangeable. When working with a list of tuples where multiple tuples share the same first element, we often need to sum the second elements of tuples that have matching first elements. Using Dictionary and For Loop This approach converts tuples to a dictionary where first elements become keys and second elements are summed as values − # List of tuples with some duplicate first elements data = [(3, 19), (7, 31), (7, 50), (1, 25.5), (1, 12)] # Create dictionary with first elements as keys, initialize to ...
Read MorePython - geometry method in Tkinter
