左側項目External Libraries中打開Lib,往下拉，因為turtle是默認攜帶的庫
打開turtle.py,找到
__all__ = (_tg_classes + _tg_screen_functions + _tg_turtle_functions + _tg_utilities + ['Terminator']) # + _math_functions)
將上面代碼注釋，新加入：
__all__= ['ScrolledCanvas', 'TurtleScreen', 'Screen', 'RawTurtle', 'Turtle', 'RawPen', 'Pen', 'Shape', 'Vec2D', 'back', 'backward', 'begin_fill', 'begin_poly', 'bk', 'addshape', 'bgcolor', 'bgpic', 'bye', 'clearscreen', 'colormode', 'delay', 'exitonclick', 'getcanvas', 'getshapes', 'listen', 'mainloop', 'mode', 'numinput', 'onkey', 'onkeypress', 'onkeyrelease', 'onscreenclick', 'ontimer', 'register_shape', 'resetscreen', 'screensize', 'setup', 'Terminator', 'setworldcoordinates', 'textinput', 'title', 'tracer', 'turtles', 'update', 'window_height', 'window_width', 'write_docstringdict', 'done', 'circle', 'clear', 'clearstamp', 'clearstamps', 'clone', 'color', 'degrees', 'distance', 'dot', 'down', 'end_fill', 'end_poly', 'fd', 'fillcolor', 'filling', 'forward', 'get_poly', 'getpen', 'getscreen', 'get_shapepoly', 'getturtle', 'goto', 'heading', 'hideturtle', 'home', 'ht', 'isdown', 'isvisible', 'left', 'lt', 'onclick', 'ondrag', 'onrelease', 'pd', 'pen', 'pencolor', 'pendown', 'pensize', 'penup', 'pos', 'position', 'pu', 'radians', 'right', 'reset', 'resizemode', 'rt', 'seth', 'setheading', 'setpos', 'setposition', 'settiltangle', 'setundobuffer', 'setx', 'sety', 'shape', 'shapesize', 'shapetransform', 'shearfactor', 'showturtle', 'speed', 'st', 'stamp', 'tilt', 'tiltangle', 'towards', 'turtlesize', 'undo', 'undobufferentries', 'up', 'width', 'write', 'xcor', 'ycor']
最后重啟pycharm即可
