Take a Break & rename files & Draw Turtle (Ucity_python)

Ucity's Python tutorial learned a few small projects, now summarize and post the code.

There are two good ways to learn Python: one is to find modules, functions, and methods of use through official documents, and one is how a Google method is implemented, such as searching for "open web in Python" and choosing the answer to the stack overflow.

　

　　1.take a break

Requirements: Set to a certain time, jump to a webpage, let the person in front of the computer rest

Steps: (1) The calculation time triggers the open page, (2) opens a specific webpage, (3) counts and loops.

ImportTime#Import Time ModuleImportWebBrowser#Importing Web ModulesTotal_breaks=3#Rest 3 timesBreak_count=0#recorded a few breaks.Print('The time is :'+time.ctime ())#the current time of the output while(Break_count<total_breaks):#number of cycles of restTime.sleep (2)#2 seconds from current timerWebbrowser.open ('https://weibo.com/')#open a Web pageBreak_count+=1#The current is the first few times to rest    Print(' the'+str (Break_count) +' Time')#output, which is the first few times of rest

　

2.rename_files

Requirements: Rename the image, remove the number

Step: (1) Get the picture name, (2) rename each picture.

ImportOs#Input ModuledefRename_files ():#Defining Functions    #(1) Get file names from a folder Step 1: Get file nameFile_list=os.listdir (R'E:\spyder\a\prank')#get a list of all files    Print(file_list)#View these listsSAVED_PATH=OS.GETCWD ()#Get Path    Print('the current working directory is:'+saved_path)#Current working directory is XX (not the directory where the picture is located)Os.chdir (R'E:\spyder\a\prank')#change to the working directory where the picture is located    #(2) for each file,rename filename Step 2: rename     forfile_nameinchFile_list:#cycle, change the name of the picture individuallyFile_name_new=file_name.translate (Str.maketrans ("',"','0123456789'))#Get rid of numbers        Print('Old name-'+file_name)#Output old name        Print('New name-'+file_name_new)#Output New nameOs.rename (file_name,file_name_new)#Replace nameOs.chdir (Saved_path)#change to the previous working directoryRename_files ()#calling Functions

3.draw Turtle

Requirements: Design Turtle motion Trajectory

Steps: (1) Design motion trajectory, (2) Design movement image

ImportTurtle as C#Input ModuledefDraw_square (Some_turtle):#Draw a rectangle     forIinchRange (1,5): Some_turtle.forward (100) Some_turtle.right (90)        defDraw_art ():#Draw This functionwindow=C.screen () Window.bgcolor (' White') Brad=C.turtle () brad.shape ('Turtle') Brad.color ('Yellow') Draw_square (Brad) Angie=C.turtle () angie.shape ('Arrow') Angie.color ('Blue') angie.circle (100) Window.exitonclick () Draw_art ()

* Do not know why, run the second time, will be error "kernel hangs, restart in."
