In this paper, the use of Python turtle module, turtle Drawing, is introduced as an example, and it is believed to be of reference value for friends who need graphic programming. Python Turtle Module Introduction:A simple drawing tool introduced in the python2.6 version, called Turtle

can use Fig.suptitle () to set the overall caption of the entire graph. 7. Line style and line widthChange the line width, color, or style.8. Basic Data distributionThe necessary operations in the EDA process.9. Contour and color grid for two-D arraysThermal image (color grid) and contour plots help visualize 2D data in many cases.10. Image adjustment, modification of edge coordinates and scaleFinally, adjust the details to make the drawing look

When using matplotlib drawing to add a formula to a picture, it is generally necessary to use the text or annotate function, combined with latex grammar ' $...$ '.For fractions, if you use \frac{}{} directly, the characters on the numerator denominator are small, as shown in the Green formula.To solve this problem, we need to use the \displaystyle, that is, using the ' $\displaystyle ... $ ', as shown in the Blue formula in the effect. However, the pr

My study notes are mainly recorded in the study opencv-python-tutorials the book of the NotesThis evening learn how OpenCV for Python plots, mainly using these functions (these functions can be in: http://docs.opencv.org/modules/core/doc/drawing_functions.html Found):Start by copying the code from the book, the code is as follows:Import NumPy as NP Import = Np.zeros (512,512,3= Cv2.line (IMG, (), (510,510)

Using Python'sTurtle (Turtle)Module drawing the first step: let Python introduce the Turtle module, the introduction of the module is to tell Python you want to use it.Import TurtleStep Two: Create the canvas. Call the pen function in turtle.t = Turtle. Pen ()Step three: Move the turtle.T.forward (50)Forward's Chinese meaning is "forward, promote." So this line o

Python libraries are numerous and constantly updated, so the most efficient way to learn these libraries is to read the official Python documentation. At the same time with the help of Google and Baidu.
