Beginner drawing heart
Learning Python, I feel that all of you are very complicated, so let me make a simple one. I directly regard the heart shape as a square + two semicircles:
So this is very simple, ten lines of code to solve:
import turtle as t
t.pensize(2)
# 笔大小2像素
t.pencolor("red")
# 颜色为红色
t.left(45)
# 45度
t.fd(200)
# 向前200直线
t.circle(100, 180)
# 画一圆半径100 弧度180
t.right(90)
# 向右90度
t.circle(100, 180)
# 再画一个圆半径100 弧度180
t.fd(200)
# 直线向前直线200
t.done()
# 绘制完成
A line of code to draw a heart
original code
print('\n'.join([''.join([('Love'[(x-y) % len('Love')] if ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3 <= 0 else ' ') for x in range(-30, 30)]) for y in range(30, -30, -1)]))
After dismantling this long string of [one line of code], the following multi-line code is obtained, and the actual running effect is the same. The code is as follows:
import time
words = input('请输出想要表达的文字:')
#例子：words = "Dear lili, Happy Valentine's Day! Lyon Will Always Love You Till The End! ♥ Forever! ♥"
for item in words.split():
#要想实现打印出字符间的空格效果，此处添加：item = item+' '
letterlist = []#letterlist是所有打印字符的总list，里面包含y条子列表list_X
for y in range(12, -12, -1):
list_X = []#list_X是X轴上的打印字符列表，里面装着一个String类的letters
letters = ''#letters即为list_X内的字符串，实际是本行要打印的所有字符
for x in range(-30, 30):#*是乘法，**是幂次方
expression = ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3
if expression <= 0:
letters += item[(x-y) % len(item)]
else:
letters += ' '
list_X.append(letters)
letterlist += list_X
print('\n'.join(letterlist))
time.sleep(1.5);However, it's a bit too monotonous. Come on, let me roll up my sleeves and do something, and simply modify the code to achieve the effect of dynamically outputting a heart-shaped sentence:
After the makeover, it looks great! The effect is as follows:
The code is as follows, if you like it, please like it, thank you ❤️! :
import time
words = input('请输出想要表达的文字:')
for item in words.split():
print('\n'.join([''.join([(item[(x-y) % len(item)] if ((x*0.05)**2+(y*0.1)**2-1)**3-(x*0.05)**2*(y*0.1)**3 <= 0 else ' ') for x in range(-30, 30)]) for y in range(12, -12, -1)]))
time.sleep(1.5)In fact, emoji like ❤️ can actually be output, but the format is not a standard heart shape, you need to adjust it yourself, you can try it yourself ^_^!
