Hello everyone, I will answer the following questions for you. Where is the center of the semicircle drawn by python turtle circle? Use turtle to draw a circle in python. Now let's take a look!
1. What does t.circle(100,180) mean?
t.circle(100, 180) is a function in the turtle library in Python, which is used to draw an arc with a radius of 100 and an angle of 180 degrees.
Wherein, the first parameter 100 represents the radius of the arc, and the second parameter 180 represents the space angle of the arc, that is, a semicircle is drawn. The function can also accept an optional third parameter, which specifies the direction in which the arc is drawn (counterclockwise by default).
The t.circle() function is one of the commonly used drawing functions in the turtle library, which can be used to draw circles, arcs and other graphics. Before using this function, you need to create a turtle object and call its penup() and pendown() methods to control the movement and drawing of the brush. For example: such as
```
import turtle as t
# Create a turtle object
pen = t.Turtle()
# Draw an arc with a radius of 100 and an angle of 180 degrees
pen.penup() # Lift up the brush scum
(0 , 0) # Move the pen to the origin of the coordinates
pen.pendown() # Drop the pen
pen.circle(100, 180) # Draw an arc
t.done() # Complete the
drawing```
2. How to draw a circle in situ with Python?
You can use the Python turtle library to draw a circle. Here is a sample bad code:
python copy code import turtle
my_turtle = turtle.Turtle()
my_turtle.circle(50)
()
In this example, we first import the turtle module and create a Turtle object named my_turtle.
Next, we call the circle method on the my_turtle object, passing in a radius of 50 means that we need to draw a circle with a radius of 50.
Finally, we call the done() method to keep the window open and wait for the user to close the window.
Running this code will open a new window and draw a circle with a radius of 50 in it.

4. How to use turtle to draw a circle in python
turtle.circle ()
The Turtle library is a very popular function library for talking about rolling and drawing images in the Python language. Imagine a little turtle, starting at the origin of a coordinate system with x as the horizontal axis and y as the vertical axis, starting at the position (0,0), it uses a The Nainian group is controlled by the Hanchangshi sleepy number command, and moves in this plane coordinate system, thus drawing graphics on its crawling path.
5. How to use the turtle library to draw different graphics, one graphic and one function, and draw different graphics according to different numbers?
You can use the turtle library in Python to draw various graphics. A simple example is given below, which defines several different functions, each of which will draw different graphics, and these graphics can be selected to be drawn by passing in different numerical parameters.
import turtle
# Painting Hall Sun Chun Square
def draw_square():
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle.forward(100)
turtle.right(90)
turtle .forward(100)
# Draw a triangle
def draw_triangle():
turtle.forward(100)
turtle.right(120)
turtle.forward(100)
turtle.right(120)
turtle.forward(100)
# Draw a circle
def draw_circle( ):
turtle.circle(50)
# Select the shape to be drawn according to the number parameter passed in
def draw_shape(num):
if num == 0:
draw_square()
elif num == 1:
draw_triangle()
elif num == 2:
draw_circle()
else:
print("Invalid number!")
# Main function, program entry
if __name__ == "__main__":
turtle.showturtle()
num = int(input("Enter a number (0-2) to draw a shape: "))
draw_shape(num)
()
The above code defines three different functions draw_square(), draw_triangle(), draw_circle(), each function will draw different graphics . In the draw_shape() function, judge which shape needs to be drawn according to the number parameter passed in. Finally, in the main function, use turtle.showturtle() to display the turtle drawing window, and call the draw_shape() function by reading the input numbers to draw the corresponding graphics. The () function is used to keep the window from closing.
You can try running the above code in an interactive environment or in a file and enter different parameters to see if they draw the graph you expect.
6. How to draw an ellipse with python turtle
1. First figure out the basic usage of the brush.
2. Then figure out the function of the ellipse.
3. Based on other people's codes, you can draw interesting graphics after debugging a few times by yourself.
code show as below:
import turtle pen=turtle.Turtle() #Define brush instance a=1 for i in range(120): if 0<=i<30 or 60<=i<90: a=a+0.2 (3) #Left Turn 3 degrees (a) and laugh at the side#Go forward with the step length of a else: a=a-0.2 (3) Youpai(a) print(pen) turtle.mainloop()
7. Python uses turtle to draw arcs
This original picture can be drawn. In other words, using him is like using a cone, the principle is actually the same, and it is completely feasible.
8. How to increase the radius of each circle drawn in python turtle drawing
import turtle#Import the sea turtle library r=10#The radius added each time is also the initial radius for i in range(9):#Batch ratio cycle stuffy turtle.penup()#Lift your pen (0,-r*( i+1))#Move on the Y axis, the mass turtle.pendown()#Put down your pen down turtle.circle(r*(i+1))#Curve into a circle, the radius increases in a certain order () #Keep the screen, do not exit
9. How to use python to draw an Audi car marker with a pen width of 10 and a circle radius of 50?
The following is the sample code for drawing the Audi logo using Python:
import turtle
# create canvas and brush
turtle.bgcolor("black")
screen = turtle.Screen()
pen = turtle.Turtle()
# Set brush properties
pen.width(10)
pen.color('Xianqiaokai silver')
# Move to the proper position
pen.end()
pen.backward(150)
pen. pendown()
# draw the first circle
pen.circle(50)
# raise the brush
pen.end()
# go ahead
(75)
# Put down the brush and start drawing
pen. pendown()
# second circle
pen.circle(50)
# raise the brush
pen.end()
# Press the brush after advancing to the specified position
(75)
pen. pendown()
# third circle
pen.circle(50)
# raise the brush
pen.end()
# go ahead
(75)
# draw the fourth circle
pen. pendown()
pen.circle(50)
# hide the brush and show the canvas
pen.hideturtle()
screen.mainloop()
In the above code, we use the turtle module to draw the Audi logo . First, we create a canvas and a brush, then set the line width of the brush properties to 10. Next, we draw four intersecting circles in turn to form the Audi logo. Finally, we hide the brush and show the canvas.
The running effect is as follows:
Program running effect display
It should be noted that when drawing a circle, use the circle() function to move the current tip of the pen to the center of the circle, and draw a circle with a radius of r from the center. Use the penup() function to raise the pen tip, and use the pendown() function to put the pen tip down. At the same time, you need to call hideturtle() to hide the brush to avoid showing the trail of the brush.
